Nikon releases the NIKKOR Z 58mm f/0.95 S Noct, a fast, standard prime, manual-focus lens for the Nikon Z mount system

October 10, 2019

The pinnacle of the S-Line of NIKKOR Z lenses, which exemplifies Nikon's mission to pursue the ultimate in optical performance

TOKYO - Nikon Corporation (Nikon) is pleased to announce the release of the NIKKOR Z 58mm f/0.95 S Noct, a fast, standard prime, manual-focus lens for the Nikon Z mount system's full-frame (Nikon FX-format) mirrorless cameras.

The NIKKOR Z 58mm f/0.95 S Noct is positioned at the very top of the S-Line*1, and serves as the symbol of the superior optical performance achieved with NIKKOR Z lenses. It takes advantage of the superior design flexibility made possible by the combination of the large-diameter (inner diameter of 55 mm) Z mount and 16 mm flange focal distance to realize an f/0.95 maximum aperture, the fastest (brightest)*2 in Nikon history. The design intent behind the AI Noct Nikkor 58mm f/1.2*3 standard prime lens, which was released in 1977 and so well received for its ability to reproduce sharp and clear point images, has been carried over to this new Noct lens that pursues outstanding optical performance and incredible rendering performance in terms of point-image reproduction characteristics, resolution, and bokeh effects, maximizing these characteristics from its f/0.95 maximum aperture.

The optics for this lens are constructed of 17 elements in 10 groups, for which four ED glass elements and three aspherical lens elements - including new large-diameter ground aspherical lens elements made of high-refractive-index glass materials molded with great precision - are employed. These elements realize a high degree of correction for various types of aberration, including distortion and spherical aberration. In addition, Nikon's exclusive anti-reflection coatings, ARNEO Coat and Nano Crystal Coat, have been adopted. The combination of these two coating technologies effectively reduces ghost and flare generated by incident light for incredibly sharp and clear images.

*1 The S-Line is a newly designated grade of NIKKOR Z lenses that adhere to a new benchmark in optical performance, redefining design principles and quality control.

*2 Among interchangeable lenses for Nikon cameras.

*3 A lens named for musical compositions known as nocturnes and optimized for nighttime photography with a fast maximum aperture and superior point-image reproduction characteristics.

The lens is designed with machined metal exterior components and a yellow engraved "Noct" that give the lens an elegant appearance that matches the refined quality of the engineering. It is equipped with focus and control rings that rotate smoothly for operation with a precision feel, and supports the skilled use in a wide variety of situations and conditions expected of the pinnacle of the S-Line.

The NIKKOR Z 58mm f/0.95 S Noct, which pursues the ultimate in optical performance, enables new forms of imaging expression with stills and movies for those who primarily concentrate on portrait, night landscape, and starscape photography.

The dedicated trunk case bearing the Noct logo supplied with the lens can be used to store not only the NIKKOR Z 58mm f/0.95 S Noct, but also contains an additional storage compartment beneath the trunk's inner cover, which is illustrated with a cross-section of the lens. This case has been designed for flexible use that responds to a variety of needs.

Primary features:

  • The symbol of the Nikon Z mount system's optical performance with the fastest maximum aperture (f/0.95) in Nikon history
  • The extremely shallow depth of field and large and beautiful bokeh possible only with a maximum aperture of f/0.95
  • Outstanding resolution along the focal plane at any shooting distance from close-up to infinity, even at maximum aperture
  • Unique spatial expression with ideal blur characteristics as the degree of bokeh transitions smoothly and naturally with increasing distance from the focal plane
  • Incredible point-image reproduction characteristics that render point light sources as point images, making sharp and clear night landscapes and starscapes possible, even at maximum aperture
  • Adoption of large-diameter ground aspherical lens elements made of glass with a high refractive index enables powerful, yet extremely precise, aberration correction
  • The use of two of Nikon's exclusive anti-reflection coatings, ARNEO Coat and Nano Crystal Coat, effectively suppresses ghost and flare
  • Control and focus rings that rotate smoothly and quietly, and with the proper torque, for optimal operability with still-image and movie recording
  • A convenient L-Fn (lens function) button to which a variety of functions can be assigned
  • Equipped with a lens info panel that can be used even in dark surroundings to confirm information such as aperture value, shooting distance, and depth of field without looking through the camera's viewfinder
  • Designed with consideration given to dust- and drip-resistance, featuring a fluorine coat that effectively repels dust, water droplets, grease, and dirt
  • An electromagnetic diaphragm mechanism enables extremely precise aperture control
  • A felt-lined lens hood (supplied) effectively reduces reflections off the inner surface of the hood

A COVETED CLASSIC REBORN AS A MODERN MASTERPIECE: NIKON RELEASES THE FASTEST NIKKOR LENS EVER CREATED, THE NIKKOR Z 58MM f/0.95 S NOCT

MELVILLE, NY (October 10, 2019 at 12:01 AM EDT) – Today, Nikon Inc. announced the fastest NIKKOR lens ever made, the new NIKKOR Z 58mm f/0.95 S Noct lens. The 58mm Noct is a one-of-a-kind lens that pays homage to the extraordinary optical legacy that the previous Noct-NIKKOR 58mm f/1.2 lens established, while demonstrating the superiority and potential of the Nikon Z Mount. Created for the most discerning photographers, the new Noct lens is an exclusively manual focus prime lens with an incredible maximum aperture of f/0.95 for a truly dramatic depth of field and next-level low light performance.

The NIKKOR Z 58mm f/0.95 S Noct is in a class of its own, offering low light ability and extreme sharpness that excels in the hands of a capable creator. From stunning portraits to landscapes or astrophotography, all images are rendered beautifully thanks to its vast depth-of field control, seductive bokeh and superb point-image reproduction.

“This is why the Z mount was created. The Noct is a testament to Nikon’s commitment to optical innovation driven by more than a century of expertise,” said Jay Vannatter, Executive Vice President, Nikon Inc. “We promised a new dimension of optical performance for the Nikon Z series and NIKKOR Z lens lineup, and by announcing our fastest NIKKOR lens ever made, the NIKKOR Z 58mm f/0.95 S Noct, we are making this claim a reality.”

THE NEWEST ADDITION TO S-LINE OF NIKKOR Z LENSES

The NIKKOR Z 58mm f/0.95 S Noct joins as the apex to the ever-expanding series of S-Line lenses, which also includes the recently announced NIKKOR Z 24mm f/1.8 S and NIKKOR Z 85mm f/1.8 S, all hailed for their sharpness and optical performance.

A LEGENDARY LENS REBORN

The original Noct-NIKKOR 58mm f/1.2 was released in 1977, its name said to be derived from “Nocturne.” Made for nighttime photography, this lens became renowned for its ability to reproduce point light sources as point images. The design of the new Noct lens evolves with the most advanced optical technology for photographers and videographers, boasting an immense f/0.95 maximum aperture, staggering low light ability and enticing bokeh characteristics.

The NIKKOR Z 58mm f/0.95 S Noct implores an extensive depth of field, producing elaborate bokeh and blur characteristics with good continuity for more compelling, three-dimensional imaging. Even when the distance between the subject and the background are insufficient, the new 58mm Noct lens can still capture sharp images with beautiful background blur due to the reproduction of an extremely sharp focus plane and vast shallow depth of field. Additionally, shooting point light sources at maximum aperture would normally produce sagittal coma flare. However, with the new Noct lens the causes of sagittal coma flare are eliminated across the entire frame with point light sources being reproduced as tack-sharp point images even at the peripheries, for clear and crisp night landscapes and astronomical shots.

A lens like the new NIKKOR Z 58mm f/0.95 S Noct is possible today because of the large Z mount, which allows for more light capture and faster data sharing between lens and camera, as well as improved flexibility for lens optics and design. The new Noct lens also boasts a large-diameter ground aspherical lens element crafted from the finest glass with outstanding surface accuracy, providing a higher refractive index that would otherwise be unobtainable. This pro-level lens is constructed with an optical formula consisting of 17 elements in 10 groups, ensuring a well-balanced lens that delivers incredibly sharp results.

Like the NIKKOR Z 24-70mm f/2.8 S lens announced earlier this year, the NIKKOR Z 58mm f/0.95 S Noct lens includes an ARNEO Coat, which provides anti-reflection performance to combat incident light reaching the lens surface from a vertical direction. Alongside the Nano Crystal Coat, which effectively reduces incident light from a diagonal direction, the new Noct lens can capture clear and sharp content with minimal ghosting and flare effects across a wide variety of backlit situations that are normally challenging. Additionally, the NIKKOR Z 58mm f/0.95 S Noct includes a lens information panel allowing photographers and videographers to confirm aperture, focus distance and depth of field at a glance. Users will also enjoy the increased number of functions that can be assigned to the lens Fn button, matching the Fn1/Fn2 buttons on both the Z 7 and Z 6 cameras. Additionally, an electromagnetic diaphragm mechanism is incorporated, providing stable aperture control even during continuous shooting. The fluorine coat of the new Noct lens acts as a dust, dirt and moisture repellent coating.

In addition to the refined and durable exterior design, the NIKKOR Z 58mm f/0.95 S Noct offers excellent operability and a feeling of precision in hand. The focus ring enables accurate manual focusing, allowing for the appropriate amount of torque and a large rotation angle, even for the extremely shallow depth of field afforded at f/0.95. The new Noct lens also adopts a control ring, where functions like aperture setting, and exposure compensation can be assigned. Furthermore, the inside of the lens hood is felt-lined, delivering clear rendering by effectively preventing light reflection inside the hood.

From the editor

A flagship model in the Nikon's lineup. To a greater extent it is a demonstration of the company's design capabilities, rather than some kind of practical lens that could be used by a fairly wide range of professionals or wealthy amateur photographers. Heavy weight prevents the lens from being used for any lengthy handheld shooting. The list of genres that can be shot with this lens is quite limited - reportage and event photography are not possible due to the heavy weight and lack of autofocus, the ultra-fast speed is not required for landscape or architectural photography, and a wider angle of view is desirable. This model will find its best use, perhaps, only for studio portrait photography. When mounted on a tripod, in a studio with controlled lighting, virtually any shutter speed is possible to obtain the correct exposure, eliminating the need to take advantage of the lens's ultra-high speed. The studio use also won't require weather sealing and fluorine coating that this lens has.

Chromatic aberration

There are two kinds of chromatic aberration: longitudinal and lateral. Longitudinal chromatic aberration is a variation in location of the image plane with changes in wave lengths. It produces the image point surrounded by different colors which result in a blurred image in black-and-white pictures. Lateral chromatic aberration is a variation in image size or magnification with wave length. This aberration does not appear at axial image points but toward the surrounding area, proportional to the distance from the center of the image field. Stopping down the lens has only a limited effect on these aberrations.

Spherical aberration

Spherical aberration is caused because the lens is round and the film or image sensor is flat. Light entering the edge of the lens is more severely refracted than light entering the center of the lens. This results in a blurred image, and also causes flare (non-image forming internal reflections). Stopping down the lens minimizes spherical aberration and flare, but introduces diffraction.

Astigmatism

Astigmatism in a lens causes a point in the subject to be reproduced as a line in the image. The effect becomes worse towards the corner of the image. Stopping down the lens has very little effect.

Coma

Coma in a lens causes a circular shape in the subject to be reproduced as an oval shape in the image. Stopping down the lens has almost no effect.

Curvature of field

Curvature of field is the inability of a lens to produce a flat image of a flat subject. The image is formed instead on a curved surface. If the center of the image is in focus, the edges are out of focus and vice versa. Stopping down the lens has a limited effect.

Distortion

Distortion is the inability of a lens to capture lines as straight across the entire image area. Barrel distortion causes straight lines at the edges of the frame to bow toward the center of the image, producing a barrel shape. Pincushion distortion causes straight lines at the edges of the frame to curve in toward the lens axis. Distortion, whether barrel or pincushion type, is caused by differences in magnification; stopping down the lens has no effect at all.

The term "distortion" is also sometimes used instead of the term "aberration". In this case, other types of optical aberrations may also be meant, not necessarily geometric distortion.

Diffraction

Classically, light is thought of as always traveling in straight lines, but in reality, light waves tend to bend around nearby barriers, spreading out in the process. This phenomenon is known as diffraction and occurs when a light wave passes by a corner or through an opening. Diffraction plays a paramount role in limiting the resolving power of any lens.

Doublet

Doublet is a lens design comprised of two elements grouped together. Sometimes the two elements are cemented together, and other times they are separated by an air gap. Examples of this type of lens include achromatic close-up lenses.

Dynamic range

Dynamic range is the maximum range of tones, from darkest shadows to brightest highlights, that can be produced by a device or perceived in an image. Also called tonal range.

Resolving power

Resolving power is the ability of a lens, photographic emulsion or imaging sensor to distinguish fine detail. Resolving power is expressed in terms of lines per millimeter that are distinctly recorded in the final image.

Vignetting

Vignetting is the darkening of the corners of an image relative to the center of the image. There are three types of vignetting: optical, mechanical, and natural vignetting.

Optical vignetting is caused by the physical dimensions of a multi-element lens. Rear elements are shaded by elements in front of them, which reduces the effective lens opening for off-axis incident light. The result is a gradual decrease of the light intensity towards the image periphery. Optical vignetting is sensitive to the aperture and can be completely cured by stopping down the lens. Two or three stops are usually sufficient.

Mechanical vignetting occurs when light beams are partially blocked by external objects such as thick or stacked filters, secondary lenses, and improper lens hoods.

Natural vignetting (also known as natural illumination falloff) is not due to the blocking of light rays. The falloff is approximated by the "cosine fourth" law of illumination falloff. Wide-angle rangefinder designs are particularly prone to natural vignetting. Stopping down the lens cannot cure it.

Flare

Bright shapes or lack of contrast caused when light is scattered by the surface of the lens or reflected off the interior surfaces of the lens barrel. This is most often seen when the lens is pointed toward the sun or another bright light source. Flare can be minimized by using anti-reflection coatings, light baffles, or a lens hood.

Ghosting

Glowing patches of light that appear in a photograph due to lens flare.

Retrofocus design

Design with negative lens group(s) positioned in front of the diaphragm and positive lens group(s) positioned at the rear of the diaphragm. This provides a short focal length with a long back focus or lens-to-film distance, allowing for movement of the reflex mirror in SLR cameras. Sometimes called an inverted telephoto lens.

Anastigmat

A photographic lens completely corrected for the three main optical aberrations: spherical aberration, coma, and astigmatism.

By the mid-20th century, the vast majority of lenses were close to being anastigmatic, so most manufacturers stopped including this characteristic in lens names and/or descriptions and focused on advertising other features (anti-reflection coating, for example).

Rectilinear design

Design that does not introduce significant distortion, especially ultra-wide angle lenses that preserve straight lines and do not curve them (unlike a fisheye lens, for instance).

Focus shift

A change in the position of the plane of optimal focus, generally due to a change in focal length when using a zoom lens, and in some lenses, with a change in aperture.

Transmittance

The amount of light that passes through a lens without being either absorbed by the glass or being reflected by glass/air surfaces.

Modulation Transfer Function (MTF)

When optical designers attempt to compare the performance of optical systems, a commonly used measure is the modulation transfer function (MTF).

The components of MTF are:

The MTF of a lens is a measurement of its ability to transfer contrast at a particular resolution from the object to the image. In other words, MTF is a way to incorporate resolution and contrast into a single specification.

Knowing the MTF curves of each photographic lens and camera sensor within a system allows a designer to make the appropriate selection when optimizing for a particular resolution.

Veiling glare

Lens flare that causes loss of contrast over part or all of the image.

Anti-reflection coating

When light enters or exits an uncoated lens approximately 5% of the light is reflected back at each lens-air boundary due to the difference in refractive index. This reflected light causes flare and ghosting, which results in deterioration of image quality. To counter this, a vapor-deposited coating that reduces light reflection is applied to the lens surface. Early coatings consisted of a single thin film with the correct refractive index differences to cancel out reflections. Multi-layer coatings, introduced in the early 1970s, are made up of several such films.

Benefits of anti-reflection coating:

Circular fisheye

Produces a 180° angle of view in all directions (horizontal, vertical and diagonal).

The image circle of the lens is inscribed in the image frame.

Diagonal (full-frame) fisheye

Covers the entire image frame. For this reason diagonal fisheye lenses are often called full-frame fisheyes.

Extension ring

Extension rings can be used singly or in combination to vary the reproduction ratio of lenses. They are mounted between the camera body and the lens. As a rule, the effect becomes stronger the shorter the focal length of the lens in use, and the longer the focal length of the extension ring.

View camera

A large-format camera with a ground-glass viewfinder at the image plane for viewing and focusing. The photographer must stick his head under a cloth hood in order to see the image projected on the ground glass. Because of their 4x5-inch (or larger) negatives, these cameras can produce extremely high-quality results. View cameras also usually support movements.

Shutter speed ring with "F" setting

The "F" setting disengages the leaf shutter and is set when using only the focal plane shutter in the camera body.

Catch for disengaging cross-coupling

The shutter and diaphragm settings are cross-coupled so that the diaphragm opens to a corresponding degree when faster shutter speeds are selected. The cross-coupling can be disengaged at the press of a catch.

Cross-coupling button

With the cross-coupling button depressed speed/aperture combinations can be altered without changing the Exposure Value setting.

M & X sync

The shutter is fully synchronized for M- and X-settings so that you can work with flash at all shutter speeds.

In M-sync, the shutter closes the flash-firing circuit slightly before it is fully open to catch the flash at maximum intensity. The M-setting is used for Class M flash bulbs.

In X-sync, the flash takes place when the shutter is fully opened. The X-setting is used for electronic flash.

X sync

The shutter is fully synchronized for X-setting so that you can work with flash at all shutter speeds.

In X-sync, the flash takes place when the shutter is fully opened. The X-setting is used for electronic flash.

MF

Sorry, no additional information is available.

Aspherical elements

Aspherical elements (ASPH, XA, XGM) are used in wide-angle lenses for correction of distortion and in large-aperture lenses for correction of spherical aberration, astigmatism and coma, thus ensuring excellent sharpness and contrast even at fully open aperture. The effect of the aspherical element is determined by its position within the optical formula: the more the aspherical element moves away from the aperture stop, the more it influences distortion; close to the aperture stop it can be particularly used to correct spherical aberration. Aspherical element can substitute one or several regular spherical elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Use of aspherical elements has its downsides: it leads to non-uniform rendering of out-of-focus highlights. This effect usually appears as "onion-like" texture of concentric rings or "wooly-like" texture and is caused by very slight defects in the surface of aspherical element. It is difficult to predict such effect, but usually it occurs when the highlights are small enough and far enough out of focus.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Low dispersion elements

Low dispersion elements (ED, LD, SD, UD etc) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. This type of glass exhibits low refractive index, low dispersion, and exceptional partial dispersion characteristics compared to standard optical glass. Two lenses made of low dispersion glass offer almost the same performance as one fluorite lens.

Canon's Super UD, Nikon's Super ED, Pentax' Super ED, Sigma's FLD ("F" Low Dispersion), Sony' Super ED and Tamron's XLD glasses are the highest level low dispersion glasses available with extremely high light transmission. These optical glasses have a performance equal to fluorite glass.

High-refraction low-dispersion elements

High-refraction low-dispersion elements (HLD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

High Index, High Dispersion elements

High Index, High Dispersion elements (HID) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Anomalous partial dispersion elements

Anomalous partial dispersion elements (AD) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture.

Fluorite elements

Synthetic fluorite elements (FL) minimize chromatic aberrations and ensure excellent sharpness and contrast even at fully open aperture. Compared with optical glass, fluorite lenses have a considerably lower refraction index, low dispersion and extraordinary partial dispersion, and high transmission of infrared and ultraviolet light. They are also significantly lighter than optical glass.

According to Nikon, fluorite easily cracks and is sensitive to temperature changes that can adversely affect focusing by altering the lens' refractive index. To avoid this, Canon, as the manufacturer most widely using fluorite in its telephoto lenses, never uses fluorite in the front and rear lens elements, and the white coating is applied to the lens barrels to reflect light and prevent the lens from overheating.

Short-wavelength refractive elements

High and specialized-dispersion elements (SR) refract light with wavelengths shorter than that of blue to achieve highly precise chromatic aberration compensation. This technology also results in smaller and lighter lenses.

Blue Spectrum Refractive Optics

Organic Blue Spectrum Refractive Optics material (BR Optics) placed between convex and concave elements made from conventional optical glass provides more efficient correction of longitudinal chromatic aberrations in comparison with conventional technology.

Diffraction elements

Diffraction elements (DO, PF) cancel chromatic aberrations at various wavelengths. This technology results in smaller and lighter lenses in comparison with traditional designs with no compromise in image quality.

High refractive index elements

High refractive index elements (HR, HRI, XR etc) minimize field curvature and spherical aberration. High refractive index element can substitute one or several regular elements to achieve similar or better optical results, which allows to develop more compact and lightweight lenses.

Apodization element

Apodization element (APD) is in fact a radial gradient filter. It practically does not change the characteristics of light beam passing through its central part but absorbs the light at the periphery. It sort of softens the edges of the aperture making the transition from foreground to background zone very smooth and results in very attractive, natural looking and silky smooth bokeh.

Unable to follow the link

You are already on the page dedicated to this lens.

Cannot perform comparison

Cannot compare the lens to itself.

Image stabilizer

A technology used for reducing or even eliminating the effects of camera shake. Gyro sensors inside the lens detect camera shake and pass the data to a microcomputer. Then an image stabilization group of elements controlled by the microcomputer moves inside the lens and compensates camera shake in order to keep the image static on the imaging sensor or film.

The technology allows to increase the shutter speed by several stops and shoot handheld in such lighting conditions and at such focal lengths where without image stabilizer you have to use tripod, decrease the shutter speed and/or increase the ISO setting which can lead to blurry and noisy images.

Original name

Lens name as indicated on the lens barrel (usually on the front ring). With lenses from film era, may vary slightly from batch to batch.

Format

Format refers to the shape and size of film or image sensor.

35mm is the common name of the 36x24mm film format or image sensor format. It has an aspect ratio of 3:2, and a diagonal measurement of approximately 43mm. The name originates with the total width of the 135 film which was the primary medium of the format prior to the invention of the full frame digital SLR. Historically the 35mm format was sometimes called small format to distinguish it from the medium and large formats.

APS-C is an image sensor format approximately equivalent in size to the film negatives of 25.1x16.7mm with an aspect ratio of 3:2.

Medium format is a film format or image sensor format larger than 36x24mm (35mm) but smaller than 4x5in (large format).

Angle of view

Angle of view describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

As the focal length changes, the angle of view also changes. The shorter the focal length (eg 18mm), the wider the angle of view. Conversely, the longer the focal length (eg 55mm), the smaller the angle of view.

A camera's angle of view depends not only on the lens, but also on the sensor. Imaging sensors are sometimes smaller than 35mm film frame, and this causes the lens to have a narrower angle of view than with 35mm film, by a certain factor for each sensor (called the crop factor).

This website does not use the angles of view provided by lens manufacturers, but calculates them automatically by the following formula: 114.6 * arctan (21.622 / CF * FL),

where:

CF – crop-factor of a sensor,
FL – focal length of a lens.

Mount

A lens mount is an interface — mechanical and often also electrical — between a camera body and a lens.

A lens mount may be a screw-threaded type, a bayonet-type, or a breech-lock type. Modern camera lens mounts are of the bayonet type, because the bayonet mechanism precisely aligns mechanical and electrical features between lens and body, unlike screw-threaded mounts.

Lens mounts of competing manufacturers (Canon, Leica, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance (distance from the mechanical rear end surface of the lens mount to the focal plane) is also different.

Lens construction

Lens construction – a specific arrangement of elements and groups that make up the optical design, including type and size of elements, type of used materials etc.

Element - an individual piece of glass which makes up one component of a photographic lens. Photographic lenses are nearly always built up of multiple such elements.

Group – a cemented together pieces of glass which form a single unit or an individual piece of glass. The advantage is that there is no glass-air surfaces between cemented together pieces of glass, which reduces reflections.

Focal length

The focal length is the factor that determines the size of the image reproduced on the focal plane, picture angle which covers the area of the subject to be photographed, depth of field, etc.

Speed

The largest opening or stop at which a lens can be used is referred to as the speed of the lens. The larger the maximum aperture is, the faster the lens is considered to be. Lenses that offer a large maximum aperture are commonly referred to as fast lenses, and lenses with smaller maximum aperture are regarded as slow.

In low-light situations, having a wider maximum aperture means that you can shoot at a faster shutter speed or work at a lower ISO, or both.

Closest focusing distance

The minimum distance from the focal plane (film or sensor) to the subject where the lens is still able to focus.

Closest working distance

The distance from the front edge of the lens to the subject at the maximum magnification.

Magnification ratio

Determines how large the subject will appear in the final image. Magnification is expressed as a ratio. For example, a magnification ratio of 1:1 means that the image of the subject formed on the film or sensor will be the same size as the subject in real life. For this reason, a 1:1 ratio is often called "life-size".

Manual diaphragm

The diaphragm must be stopped down manually by rotating the detent aperture ring.

Preset diaphragm

The lens has two rings, one is for pre-setting, while the other is for normal diaphragm adjustment. The first ring must be set at the desired aperture, the second ring then should be fully opened for focusing, and turned back for stop down to the pre-set value.

Semi-automatic diaphragm

The lens features spring mechanism in the diaphragm, triggered by the shutter release, which stops down the diaphragm to the pre-set value. The spring needs to be reset manually after each exposure to re-open diaphragm to its maximum value.

Automatic diaphragm

The camera automatically closes the diaphragm down during the shutter operation. On completion of the exposure, the diaphragm re-opens to its maximum value.

Fixed diaphragm

The aperture setting is fixed at F/0.95 on this lens, and cannot be adjusted.

Number of blades

As a general rule, the more blades that are used to create the aperture opening in the lens, the rounder the out-of-focus highlights will be.

Some lenses are designed with curved diaphragm blades, so the roundness of the aperture comes not from the number of blades, but from their shape. However, the fewer blades the diaphragm has, the more difficult it is to form a circle, regardless of rounded edges.

At maximum aperture, the opening will be circular regardless of the number of blades.

Weight

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

Maximum diameter x Length

Excluding case or pouch, caps and other detachable accessories (lens hood, close-up adapter, tripod adapter etc.).

For lenses with collapsible design, the length is indicated for the working (retracted) state.

Weather sealing

A rubber material which is inserted in between each externally exposed part (manual focus and zoom rings, buttons, switch panels etc.) to ensure it is properly sealed against dust and moisture.

Lenses that accept front mounted filters typically do not have gaskets behind the filter mount. It is recommended to use a filter for complete weather resistance when desired.

Fluorine coating

Helps keep lenses clean by reducing the possibility of dust and dirt adhering to the lens and by facilitating cleaning should the need arise. Applied to the outer surface of the front lens element over multi-coatings.

Filters

Lens filters are accessories that can protect lenses from dirt and damage, enhance colors, minimize glare and reflections, and add creative effects to images.

Lens hood

A lens hood or lens shade is a device used on the end of a lens to block the sun or other light source in order to prevent glare and lens flare. Flare occurs when stray light strikes the front element of a lens and then bounces around within the lens. This stray light often comes from very bright light sources, such as the sun, bright studio lights, or a bright white background.

The geometry of the lens hood can vary from a plain cylindrical or conical section to a more complex shape, sometimes called a petal, tulip, or flower hood. This allows the lens hood to block stray light with the higher portions of the lens hood, while allowing more light into the corners of the image through the lowered portions of the hood.

Lens hoods are more prominent in long focus lenses because they have a smaller viewing angle than that of wide-angle lenses. For wide angle lenses, the length of the hood cannot be as long as those for telephoto lenses, as a longer hood would enter the wider field of view of the lens.

Lens hoods are often designed to fit onto the matching lens facing either forward, for normal use, or backwards, so that the hood may be stored with the lens without occupying much additional space. In addition, lens hoods can offer some degree of physical protection for the lens due to the hood extending farther than the lens itself.

Teleconverters

Teleconverters increase the effective focal length of lenses. They also usually maintain the closest focusing distance of lenses, thus increasing the magnification significantly. A lens combined with a teleconverter is normally smaller, lighter and cheaper than a "direct" telephoto lens of the same focal length and speed.

Teleconverters are a convenient way of enhancing telephoto capability, but it comes at a cost − reduced maximum aperture. Also, since teleconverters magnify every detail in the image, they logically also magnify residual aberrations of the lens.

Lens caps

Scratched lens surfaces can spoil the definition and contrast of even the finest lenses. Lens covers are the best and most inexpensive protection available against dust, moisture and abrasion. Safeguard lens elements - both front and rear - whenever the lens is not in use.
