Manufacturer description

Amstelveen, The Netherlands, August 20, 2003 - Canon, a leader in photographic and imaging technology, today launches the EOS 300D 6.3 Megapixel digital SLR. The lightest and most compact digital EOS camera ever is expected to ship with a price of approximately 1,200 EURO. "Canon expects 400-500% growth in the digital SLR segment from 2002 to 2003 in terms of shipping volume2," says Hiroshi Komatsuzaki, Head of Canon Consumer Imaging Europe. "The EOS 300D will play a key strategic role in this growth. By dropping the price so significantly, Canon is very deliberately putting high performance EOS digital technology into the hands of the consumer at a time of accelerating demand for high performance digital cameras".

The EOS 300D bundles proven high performance technologies (such as seven-point, high-speed predictive auto focus, 2.5 frame per second burst rate, 35-zone metering and DIGIC image processor) into a camera affordable to everybody.

Canon has declared the EOS 300D to be the single most important consumer SLR since the AE1 in 1976. Just as the AE1 triggered an SLR revolution by being the world's first camera with an embedded microcomputer, Canon believes the EOS 300D will be seen as the point in history when the SLR market shifted irrevocably to digital.

Precision optics, unrivalled sensor quality

At the front end of the EOS 300D is the lens system and digital sensor. Film EOS users considering the move to digital will be pleased to learn the EOS 300D works seamlessly with any of Canon's renowned EF lenses, of which there are currently more than 60.

An APS-C sized sensor gives the camera a 1.6x magnification over 35mm film format. In order to furnish EOS 300D customers with the equivalent 28-90mm zoom range so popular with 35mm film EOS users, a new EF-S 18-55 f/3.5-5.6 lens has been specially developed. This lens takes advantage of the compact sensor size, employing a 'short back focus system' which mounts the lens closer to the sensor than previous models. This provides high-quality images in a remarkably low-weight, short-length lens.

The 6.3 Megapixel CMOS sensor is almost identical to that found in the EISA award-winning EOS 10D which remains the benchmark for image quality. ISO speeds of 100, 200, 400, 800 and 1600 are selectable, giving film users a film speed range with which they will be comfortable.

Print straight from the camera

The EOS 300D is the first digital EOS camera to support the vendor-independant PictBridge print standard from launch date. Lab-quality prints can now be produced without the need for a computer by directly connecting the EOS 300D to compatible photo printers via standard USB cable. A large 1.8" LCD is used to select and review photographs to be printed and set print variables.

Fast image processing with superb results

Underpinning the camera's technical superiority is Canon's high-speed DIGIC (Digital Image Core) processor. In the days of film, image processing was the role of film companies and mini-labs. With digital, the critical role of image processing must be handled by the camera. Complex algorithms required to accurately process functions such as white balance and color rendition are integrated into the DIGIC processor, resulting in high quality images with no trade-off in camera responsiveness. "A great digital image requires both quality raw ingredients and quality processing" says Komatsuzaki. "Superior lens and sensor technologies ensure the best raw ingredients. It is what DIGIC does with these that gives the EOS 300D the edge".

Wide area, high speed focusing

7 selectable focusing points give an ultra wide AF area generally only found in advanced SLRs. Focusing modes include One-Shot AF (for fast, accurate single-shot focusing), and AI AF which can automatically switch to AI servo AF for continuous tracking of subject movement - well suited to sports photography. A Manual Focus override is selectable from the lens.

High-end exposure control

The EOS 300D boasts 35 zone TTL metering, essentially covering the full frame. Three metering modes (evaluative, partial, and centre weighted average) assure balanced exposures in every situation. Along with the full range of automated and manual shooting modes expected in a high-end SLR, the EOS 300D features Programmed Image Control modes such as Night Portrait, Sports, Close-up, Landscape, Portrait and Flash OFF. A built-in automatic flash pops up nearly 90mm above the optical axis to lessen the chance of red-eye for better flash photos.

Shooting adaptability

The EOS 300D is superbly specified to deliver outstanding results in virtually any shooting situation. The camera has a shutter speed range of 1/4000 - 30 seconds, bulb and high speed x-sync at 1/200s. Simultaneous recording to both RAW and JPEG (middle/fine) formats is possible, while 2GB and higher CompactFlash cards, Types I and II, are supported. Optional wired or infra red wireless remote control is available. Adobe RGB has been added to the standard sRGB colour space. There are seven Auto White Balance settings (such as cloudy, tungsten, fluorescent, etc.) plus custom White Balance and +/- 3 stop White Balance Bracketing (WB-BKT).

Comprehensive accessories, software and online access

The EOS 300D comes complete with battery pack, charger, USB cable, video cable, wide embroidered anti-slip neck strap. Purchase of the EOS 300D entitles customers to membership of the CANON iMAGE GATEWAY web portal for a 100 MB online photo album for image uploads. A full software suite is included for handling image file transfers between camera and computer, managing and printing files, and preview and conversion of RAW image files. PhotoStitch is included for seamless merging of panorama shots.

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.
