Manufacturer description #1

EOS-1Ds Mark III, replacing the 16.7-megapixel EOS-1Ds Mark II, is a professional digital SLR camera designed to meet the rigorous demands of professional portrait, merchandise, and landscape photographers.

Incorporating Canon’s 35 mm full-frame, 21.1-megapixel CMOS sensor, the EOS-1Ds Mark III realizes an exceptional level of image quality through its high image resolution, low noise, and rich color gradation, supporting an ISO range from 100 up to 1600.*1 The 35 mm sensor size allows users to fully utilize the angles of view offered by all Canon EF lenses,*2 allowing for unrestricted lens performance and a shooting feel on par with that of film SLR cameras.

In addition, the EOS-1Ds Mark III is equipped with the dual DIGIC III high-end image-processing system, enabling processing of even higher resolution image data at a speed approximately 4 times faster than the previous model. The technology also makes possible a continuous shooting speed of approximately 5 frames per second for up to 56 large JPEG images or up to 12 RAW images in a sequence. The model further realizes outstanding functionality by employing a high-speed, high-precision Area AF sensor of 19 cross-type points (f/2.8 or faster lenses) plus 26 assist points (f/5.6 or faster lenses), and a newly developed high-performance viewfinder that achieves 100% coverage and 0.76x magnification, the highest viewfinder magnification in its class.*3

The EOS-1Ds Mark III caters to the needs of pro users by offering outstanding resilience, boasting a shutter capable of withstanding 300,000 cycles. The combination of dust- and water-resistant EF lenses and accessories and Canon’s EOS Integrated Cleaning System, a complete dust reduction system, enables the camera to deliver unfailing performance under even the most grueling conditions.

Expanding upon the highly acclaimed functions of the EOS-1D Mark III launched in May 2007, the EOS-1Ds Mark III also incorporates such high-end features as a refined user interface featuring two Live View modes, which offer enhanced performance for studio photographers, and a large 3.0-inch LCD monitor, as well as a variety of system accessories to provide for a wide range of professional photography needs. The Canon EOS-1Ds Mark III will be available in Japan from late November at an open price. Canon has set initial production at 2,500 units per month.

Manufacturer description #2

Amstelveen, The Netherlands, 20 August, 2007: Canon raises the stakes in the professional photography market with the launch of the 21 Megapixel, 5 frame per second EOS-1Ds Mark III. Delivering 14-bit depth resolution from a newly developed 35mm full frame CMOS sensor, Canon’s new flagship digital SLR produces files that convert to over 100MB uncompressed 16-bit TIFF, setting a new benchmark in image resolution and sharpness for 35mm-format digital photography.

As well as producing outstanding colour rendition, Dual DIGIC III processors drive 5 fps continuous shooting for up to 56 Large JPEGs (12 RAW) – unrivalled by any other camera at this resolution. This capacity to shoot such large images uninterrupted is regarded as a big driver in switching studio photographers to the EOS platform.

The EOS-1Ds Mark III inherits the new technology platform introduced earlier this year in the EOS-1D Mark III, including 63-zone exposure metering, 19 cross-type auto focus system, a 3.0” LCD with Live View mode and EOS Integrated Cleaning System. The Highlight Tone Priority function expands dynamic range for more depth and detail in bright areas. The launch is supported with the announcement of Canon’s new ultra wide-angle lens, the Lens 2.

“Taking image quality and versatility to unprecedented levels, the EOS-1Ds Mark III redefines commercial photography conventions”, said Karz Suzuki, Head of Canon Professional Services. “The camera will strengthen Canon’s popularity amongst professional studio photographers. Culminating 20 years of EOS development, the EOS-1Ds Mark III represents a definitive moment in our company’s photographic history.”

  • 5 fps continuous shooting for up to 56 frames
  • Dual “DIGIC III” processors
  • Highlight Tone Priority
  • Auto focus system with 19 cross type sensors and 26 focus assist points
  • EOS Integrated Cleaning System
  • ISO 100-1600 (expandable to L:50 H:3200)
  • 3.0” 230K pixel LCD with Live View mode
  • Redesigned viewfinder now wider and brighter

Image quality

The EOS-1Ds Mark III produces files that exceed the standard resolution requirements of leading agencies and stock libraries. The third generation CMOS sensor incorporates a new pixel design with on-chip noise reduction circuitry to ensure high image quality all the way to ISO 1600. 14 bit A/D converters provide a total colour depth of 16,384 tones per pixel - delivering smoother gradations and more accurate colour reproduction.

The option to expand to H:3200 will be welcomed by professionals working in churches and sensitive situations where the use of flash is not permitted or desired. Where discretion is paramount, a silent drive mode delays shutter re-cocking for as long as the shutter release remains depressed.

Highlight Tone Priority mode gives wedding and landscape photographers the option to boost dynamic range for highlights when shooting above ISO 200 – reproducing more tonal detail from wedding dresses, clouds and other bright objects.

Precision and control

The auto focus system includes 19 cross-type sensors with sensitivity up to f/2.8, spread across the AF area to better accommodate off-centre subjects. An additional 26 AF assist points help with AF tracking accuracy.

The control layout includes a dedicated AF-ON button on the back of the camera, allowing users to instantly switch auto focus on when composing. The viewfinder is now brighter with a wider angle of view, while the 63-zone metering system gives photographers a greater degree of control over exposure.

New LCD with Live View

The bright 3.0” LCD monitor provides 230K pixels resolution for precise framing and reviewing. Live View mode displays a real-time image on the LCD, including a selectable grid overlay and a live histogram that simulates image exposure. For the studio environment, remote Live View lets the photographer compose, adjust settings and capture the shot from a PC using the supplied EOS utility software.

New controls and menu

The EOS-1Ds Mark III’s menu incorporates a tab structure that eliminates scrolling for vastly improved readability and ease of use. Improving on previous models, personal settings and custom functions are consolidated into 57 custom functions grouped into four logical categories. Photographers can also now see at a glance any default setting changes. The My Menu option allows photographers to store frequently used settings on a separate menu for immediate access. Settings for recently released accessories such as the Speedlite 580EX II and the Wireless File Transmitter WFT-E2 can be controlled directly from the LCD. Along with a new dedicated ISO button, ISO is permanently displayed on the top LCD panel.

Reliability

Shutter durability is increased by 50% to 300,000 cycles. A magnesium alloy casing with dust and moisture resistant seals protects the body. The EOS Integrated Cleaning System reduces, repels and removes dust from the sensor to significantly limit the need for manual cleaning. To avoid image loss, a warning alarm sounds if the memory card door is opened while images are still being written.

Connectivity

Interfaces include video out (for display in both NTSC and PAL formats – with the Live View mode ideal for live display to clients during the shoot) and USB 2.0. To prevent the USB cable becoming accidentally dislodged during shooting, a special connection secures it to the camera body.

Compatibility and accessories

As well as full compatibility with all EF lenses and EX Speedlite flashes and accessories, the EOS-1Ds Mark III is supported by the recently released Wireless File Transmitter WFT-E2. The WFT-E2 enables secure wireless uploads to FTP servers as well as remote access via HTTP and PTP protocols. The unit also connects wirelessly to external storage media and supports GPS tagging when used with a portable GPS device. For assignments where image protection and authenticity are crucial, the EOS-1Ds Mark III is compatible with the Original Data Security Kit OSK-E3.

New lens

Today’s launch coincides with the release of the EF 14mm f/2.8L II USM: Canon’s new professional L-series ultra wide-angle lens for the photographer requiring a slightly different perspective. As with many L-series lenses and the Speedlite 580EX II, the EF 14mm f/2.8L II USM incorporates environmental sealing to match that of the EOS-1Ds Mark III, creating a fully weatherproof camera system. Aspherical and UD lens elements produce exceptional image quality with improved corner-to-corner sharpness. The ring-type USM delivers fast, silent auto focus with full-time manual focus override. A circular aperture produces pleasing bokeh at wide apertures and Super Spectra coatings suppress ghosting and flare by suppressing internal reflections from lens element and sensor surfaces.

Software

The EOS-1Ds Mark III is packaged with a comprehensive software suite to streamline the photographer’s workflow. This includes Digital Photo Professional (DPP) RAW conversion/processing software for complete RAW image processing control. DPP also integrates with camera features such as the Dust Delete Data and Picture Style. The camera also comes with EOS Utility, ImageBrowser/Zoom Browser and Photostitch.

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.

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.

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 focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Manual focus override in autofocus mode

Allows to perform final focusing manually after the camera has locked the focus automatically. Note that you don't have to switch camera and/or lens to manual focus mode.

Electronic manual focus override is performed in the following way: half-press the shutter button, wait until the camera has finished the autofocusing and then focus manually without releasing the shutter button using the focusing ring.

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/ 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 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.
