Newest Otus Family Member from ZEISS Continues the Success Story

ZEISS Otus 1.4/85 expands lens family with another focal length for the highest level of professional image quality

OBERKOCHEN/Germany, 08/09/2014.

Given its focal length and speed, at first glance the new ZEISS Otus 1.4/85 appears to be a traditional portrait lens. But a closer look reveals that this is a fast all-rounder for photographers who do not accept any limitations when it comes to detail – whether it is for general studio work, or fashion, advertising, product or architectural photography. In combination with modern DSLR cameras, this lens delivers unprecedented image quality – even with an open aperture. ZEISS will present this new world-class lens for the first time to the public at photokina in Cologne/Germany from September 16 to 21, 2014.

The ZEISS Otus 1.4/85 displays all of its advantages in the classic short telephoto range, i.e. portraits and people. Its focal length, longer than a normal lens, makes it possible to keep a decent distance from the subject. Photographers who like using a landscape not just as a background will find that the ZEISS Otus 1.4/85 is no 'normal' lens, but a surprisingly powerful companion for nature photography. The edges of the picture can be used for compositional purposes at all f-stops.

Unique creative possibilities can be achieved for pictures even with little ambient light. Today's image sensors are extremely sensitive with little noise, which has significantly pushed the limits of what is possible even without artificial light. Fast lenses such as the ZEISS Otus 1.4/85 still offer enormous benefits compared with lenses that are two or three f-stops slower, especially when weak light meets fast-moving objects. Even when the light disappears completely, the ZEISS Otus 1.4/85 retains its excellent "vision", just like the owl species from which this lens family gets its name. Lenses reveal correction deficits very clearly with night shots with lots of open light sources that dominate the image. Not so with the ZEISS Otus 1.4/85: in challenging lighting situations with low ambient light, the performance edge of this lens becomes obvious.

The ZEISS Otus family of lenses and its newest member have been specially designed to meet professional photographers' most rigorous demands. Inner focusing, the dial window, and the dials' clearly recognizable yellow labeling, familiar from professional cine lenses like ARRI/ZEISS Master Prime, are just a few of the features that are setting new standards.

Optically, the ZEISS Otus series stands out for its high image quality, even with an open aperture. Specifically, that means a neutral bokeh in the background, highly detailed images without any optical artifacts, consistently high resolution power across the entire image field, no color fringing or distortion, and an extremely high image contrast all the way into the edges. The imaging performance remains almost entirely consistent for all shooting distances. High apertures can be used even for close-ups right down to a working distance of 0.65 meters.

Particularly when used in combination with high-definition 35mm DSLR cameras, ZEISS Otus lenses achieve a medium-format quality never previously achieved. In other words: lower investments, more compact gear and imaging excellence.

A view inside the ZEISS Otus 1.4/85 reveals how such quality is realized: The lens consists of eleven lens elements in nine groups. One of the lens elements has an aspheric optical surface and six are made of special glass. The optical design is based on the Planar. Because the ZEISS Otus 1.4/85 is apochromatic, chromatic diagonal aberrations (longitudinal chromatic aberrations) are corrected with the help of lens elements made of special glass with anomalous partial dispersion. As a result, practically no perceptible color fringing appears on contrast-rich edges in front of and behind the focal plane. Bright-dark transitions in the image, and in particular highlights, are rendered free of color artifacts. In addition, the variable air spaces between certain lens groups ("floating elements design") enable a consistently high imaging performance across the entire focusing range from 0.8 m to infinity.

All members of the ZEISS Otus family are characterized by the exceptional mechanical quality that sophisticated photographers are used to from ZEISS. As they were designed as manual focus lenses, it was possible to work with considerably narrower tolerances in the construction. Its smooth focus operation with the large angle of rotation allows for the finest variations when focusing. The freedom to focus – one of the most important creative elements in photography – has literally been put in the hands of the photographer as an artistic tool.

The extra-fine haptics and the precision of the focusing mechanism can only be achieved with a metal design. The robust all-metal barrel is also well equipped to deal with the rough daily work of a professional photographer, ensuring a long product life. In contrast to lenses containing a lot of plastic, which can become unbalanced over time, the metal ZEISS Otus lenses remain stable for many years. This ensures that the image quality remains consistently high. And for all photographers who in addition to the actual optics also rely on screw-on filters in their work, matching T* UV and POL filters with a diameter of 86 millimeters will be available from ZEISS for the ZEISS Otus 1.4/85.

In the fall of 2013, ZEISS presented the ZEISS Otus 1.4/55, the first representative of a high-end SLR lens series with manual focusing. This has since fulfilled its promise to be "the best standard lens on the market". Both the trade press and users were impressed.

"When we launched the Otus 1.4/55, our customers immediately understood the benefits they can get from such a lens: using their high-end full-frame camera, they can shoot pictures with a quality and look they were previously only used to getting from expensive medium-format systems," explains Christophe Casenave, Product Manager, ZEISS Camera Lenses. "With the Otus 1.4/85 we are now bringing out the second lens with this promise. Again with the Otus 1.4/85 we can say that this is a lens without any compromise on image quality. Contrast and resolution power are at the maximum level; there are no chromatic aberrations, even in the most challenging light situations; and there's no distortion, ghosting or flare. And all of this at any aperture. When you use an Otus lens, you can focus on the composition of your images. You don't need to spend any time thinking about whether the technology could possibly be a limiting factor."

The ZEISS Otus 1.4/85 will be available worldwide with EF-mount (ZE) and F-mount (ZF.2) from mid-September 2014.

Manufacturer description #2

An absolute highlight for those who appreciate the finer details - in a lens that also offers you all the creative freedoms you could possibly desire. With the ZEISS Otus® 1.4/85, you can look forward to sublime performance in almost every possible photographic situation.

The ZEISS Otus 1.4/85 is a superlative lens in every respect – just like every other focal length in the unique ZEISS Otus family. A lens designed and constructed with the comprehensive expertise and vast experience of ZEISS.

Features in portraits and finest details in textures are not the only things reproduced in perfect quality by the Otus 1.4/85. Its extremely large initial aperture is simply ideal for isolating subjects from their backgrounds. At the same time, the Otus 1.4/85 is far more than a portrait lens. Take advantage of its high speed for available light photography, its moderate angle of view for landscapes or its close focusing distance for reproductions.

The optical correction of the Otus 1.4/85 completely eliminates almost all possible forms of aberration – and makes every picture you take as exciting as the first, even after thousands of exposures.

Classification

  • Professional lens (Top class)
    • Combination of focal length and speed meets professional demands
    • Apochromatic optical design
  • Apochromatic optical design

    All glass elements in an optical system refract light in certain colors to a different extent. This leads to the effect that not all rays of light from a multi-colored subject are focused at a single imaging point – the result of this is chromatic aberration.

    In this lens, the chromatic aberration is minimized by apochromatic correction.

    A need for apochromatic correction arose with the increasing popularity of color film. Now, with high-resolution digital sensors, the need for superior control of chromatic aberrations is even more pertinent than when film changed from monochrome to color.

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.

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, Nikon, Pentax, Sony etc.) are always incompatible. In addition to the mechanical and electrical interface variations, the flange focal distance can also be different.

The flange focal distance (FFD) is the distance from the mechanical rear end surface of the lens mount to the focal plane.

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.

Floating element system

Provides correction of aberrations and ensures constantly high image quality at the entire range of focusing distances from infinity down to the closest focusing distance. It is particularly effective for the correction of field curvature that tends to occur with large-aperture, wide-angle lenses when shooting at close ranges.

The basic mechanism of the floating element system is also incorporated into the internal and rear focusing methods.

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. 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/1.4 on this lens, and cannot be adjusted.

Automatic aperture control

For Programmed Auto or Shutter-priority Auto shooting, lock the lens aperture at its minimum value.

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 and/or rear lens elements 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.
