Manufacturer description

Amstelveen, The Netherlands, 21 February, 2006: Canon today announces the EOS 30D, replacing the award winning EOS 20D. Retaining the 5fps, 8.2 Megapixel performance of its predecessor, the upgraded camera enjoys a larger, wider viewing angle 2.5” LCD, extended 100,000 shutter cycle durability, spot metering, and a variety of refinements designed to enhance the photographic experience. Targeted at an increasingly discerning population of serious creative photographers, the EOS 30D replaces a camera that already claims a significant share of the Western Europe D-SLR market, which grew by 120% in the last 12 months*1.

The EOS 30D features

  • 8.2 Megapixel APS-C size CMOS sensor
  • 5 fps and 30 large JPEG frame burst
  • 2.5”, 230K pixel, 170º wide viewing angle LCD screen
  • Picture Style image processing parameters
  • Spot metering and High Precision 9-point AF system
  • DIGIC II image processor with 0.15 sec start-up time
  • Digital Photo Professional RAW processing software
  • 100,000 cycle shutter durability and rugged magnesium alloy body
  • Simultaneous RAW and JPEG recording
  • Wide 100-3200 ISO range
  • E-TTL II Flash
  • PictBridge compatibility
  • Complete compatibility with all Canon EF and EF-S lenses and EX-series Speedlites
  • USB 2.0 Hi-Speed and Video Out connectivity

“A rapidly expanding population of serious and semi-commercial creative photographers is helping drive EOS growth,” said Mogens Jensen, Head of Canon Consumer Imaging Europe. “As well as putting many high-end pro features into their hands, the EOS 30D becomes a launching pad into the world’s most comprehensive interchangeable lens system and huge range of flash units and accessories.”

Improved performance

Many improvements over the EOS 20D are made in response to EOS 20D owner feedback. Along with the larger screen, improved durability and 3.5% area spot metering, these include Canon’s Picture Style pre-sets, Canon’s in-camera image processing standard. Picture Styles can be likened to selectable film types for different photographic expression (see appendix ‘Technologies Explained’). Frame rate is selectable between 5 and 3fps and photographers are given finer control over exposure, with ISO settings now adjustable by 1/3 stop increments rather than whole stops. A Print/Share button is included and the camera features new advanced PictBridge functionality . The maximum number of images in a folder is increased from 100 to 9,999, while the in-built flash has been upgraded to match the 100,000 shutter cycle durability, an increasingly important feature in the digital age.

Speed and image quality

The EOS 30D features Canon’s award winning CMOS sensor technology, with large 6.4µm2 pixels for wide dynamic range with low noise. Any remaining fixed pattern and random noise is dealt with by on-chip noise elimination circuitry. A low-pass filter in front of the sensor reduces false colour and moiré effects, while an infrared filter suppresses red fringing caused by sensor reflections and fog. The camera features Canon’s DIGIC II processor now found across the digital EOS range. DIGIC II maximises speed and image quality by processing uncompromisingly complex colour rendition algorithms, clearing the buffer at high speed.

EOS: The system

One of the EOS 30D’s greatest advantages is the EOS system: compatibility with all Canon EF and EF-S lenses, EX-series Speedlites and EOS accessories such as the Wireless File Transmitter WFT-E1. The EOS 30D’s EF-S lens mount allows connection to Canon’s range of lighter and wider angle lenses, including the new wide aperture EF-S 17-55mm f/2.8 IS USM standard zoom lens. Indicative of Canon’s commitment to lens development is the release today of the exceptionally fast EF 85mm f/1.2L II USM, for low light and extremely narrow depth of field photography. For high-speed processing of lossless RAW images and complete capture-to-print workflow management, the EOS 30D also comes with Canon’s latest Digital Photo Professional software.

Battery grip

To extend the EOS 30D’s 750 shot *2 battery life and increase handling options, the camera is compatible with the BG-E2 battery grip. The BG-E2 takes two Lithium-Ion battery packs for up to 2,200 *3 frames or six AA batteries *4 in the supplied BGM-E2 battery magazine. For easy vertical shooting, the BG-E2 provides additional shutter release, main dial, AE lock/FE lock and AF point selection controls.

Software

As well as the latest Digital Photo Professional RAW image processing software, the EOS 30D comes with Canon EOS Solution Disk, containing the new EOS Utility (integrating remote capture software), plus the latest versions of ZoomBrowser/ImageBrowser and PhotoStitch.

The EOS 30D includes membership of Canon’s online photo album, CANON iMAGE GATEWAY with 100MB of space for image uploads and photo sharing *5.

Picture Style

Picture Style pre-sets simplify in-camera control over image quality. Picture Style pre-sets can be likened to different film types – each one offering a different colour response. Within each easily selectable pre-set, photographers have control over sharpness, contrast, colour tone and saturation. The camera’s factory default configuration is set to deliver immediately-usable JPEG images without need for additional menu settings. Picture Style presets applied to a RAW image do not degrade the image in any way and can be revised with Canon’s Digital Photo Professional software.

The six pre-sets include: Standard – for crisp, vivid images that don’t require post-processing; Portrait – optimises colour tone and saturation and weakens sharpening to achieve attractive skin tones; Landscape – for punchier greens and blues with stronger sharpening to give a crisp edge to mountain, tree and building outlines); Neutral – ideal for post-processing; Faithful – adjusts colour to match the subject colour when shot under a colour temperature of 5200K; Monochrome – for black and white shooting with a range of filter effects (yellow, orange, red and green) and toning effects (sepia, blue, purple and green). The User Defined pre-set can be used to store up to three customised pre-sets, or any of the pre-sets available for download from Canon’s web site.

DIGIC II

Now found across the EOS range, DIGIC II is a purpose built, dedicated image processor responsible for the high speed calculations necessary in order to providing exceptionally accurate colour reproduction in real time. Canon’s second generation imaging engine, DIGIC II performs the duties of a number of separate processing units to speed processing, save space, and optimise battery life.

To avoid the trade off faced by other manufacturers between camera responsiveness and image quality, Canon has created a processor so fast it can read, process, compress and write image data back to the buffer between exposures. This allows for longer continuous bursts at maximum frame rates before the buffer fills. Moreover, each image can be subjected to the full complex processing algorithms required in order to deliver superb image quality.

CMOS

Canon’s award winning CMOS technology is one of the company’s key competitive advantages. With noise reduction circuitry at each pixel site, Canon’s CMOS sensors have lower noise and lower power consumption characteristics than CCD sensors.

CCD sensors use a bucket relay system to transfer each pixel’s accumulated electrical charge to a corresponding gutter. The operation is time consuming and draws considerable power, which limits battery life and generates unwanted heat, further increasing noise and lowering image quality.

By contrast, signal conversion in Canon’s CMOS sensors is handled by the individual amplifiers at each pixel site. Unnecessary charge transfer operations are avoided, vastly speeding up the process of getting signal to the image processor. Noise generation is reduced and power consumption limited.

Digital Photo Professional Software

Digital Photo Professional software provides high-speed processing of lossless RAW images. Processing with Digital Photo Professional allows real-time display and immediate application of image adjustments, giving control over RAW image variables such as white balance, dynamic range, exposure compensation and colour tone. The camera JPEG images can be recorded in sRGB or Adobe RGB colour space, and the Digital Photo Professional application supports sRGB, Adobe RGB and Wide Gamut RGB colour spaces. An ICC (International Colour Consortium) profile attaches automatically to RAW images converted to TIFF or JPEG images. This allows faithful reproduction of colours in software applications that support ICC profiles, such as Adobe Photoshop. For improved efficiency, a set of image adjustments can be saved as a reciepe and applied to multiple images.

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. 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.

Electromagnetic diaphragm control system

Provides highly accurate diaphragm control and stable auto exposure performance during continuous shooting.

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.
