Manufacturer description

Amstelveen, The Netherlands, 24 August 2006: Canon today announces its next generation D-SLR: the EOS 400D. Featuring a 10.1 Megapixel CMOS sensor, new EOS Integrated Cleaning System, larger and brighter 2.5” LCD and 9-point AF, the model is predicted to take the lead as the world’s most popular camera. It is positioned above the EOS 350D, currently the fastest selling SLR camera of all time.

Canon’s EOS 300D, the world’s first consumer D-SLR, kick started a digital revolution in 2003. “We are now witnessing a mass consumer trend towards D‑SLR,” said Mogens Jensen, Head of Canon Consumer Imaging Europe.

Consumer research shows it is not only existing film SLR owners now switching to digital SLR photography. “On top of the existing 21 million analogue EOS shooters, a completely new profile of consumer is adopting digital EOS and driving growth,” said Jensen. “With European household penetration having only just hit 3%, the question now is not ‘will this market be big’, but ‘how big will this market become’.”

The EOS 400D features

  • 10.1 Megapixel CMOS sensor
  • Canon’s EOS Integrated Cleaning System
  • 2.5” LCD screen with 230K pixels and 160º viewing angle
  • High-precision 9 point AF system
  • Picture Style image processing parameters
  • DIGIC II image processor with 0.2 sec start up
  • Digital Photo Professional RAW processing software
  • Compact and Lightweight body
  • Fully compatible with all Canon EF and EF-S lenses and EX-series Speedlites

Canon is the only D-SLR brand to own and manufacture the sensor, processor and lenses in house. “EOS photographers benefit from 20 years of ongoing research investment into EOS,” said Jensen. “EOS photographers have the great advantage of owning a system camera in which every element is designed at a very fundamental level to work as a balanced, integrated whole. It is one reason why more than 70% of registered photographers at the Athens Olympics shot on EOS.” With EOS, Canon aims to provide consumers with the widest and most expandable camera system available, including over 60 EF lenses and Speedlite flash units.

Improved Performance

As well as the EOS Integrated Cleaning System, the EOS 400D incorporates a number of developments over the EOS 350D. Resolution increases from 8.0 to 10.1 Megapixels, using the superior hi-sensitivity, hi-speed, low-noise CMOS technology now found in all six EOS Digital models. At nearly twice the size of the EOS 350D display, the 2.5” hi-resolution LCD is the brightest in the EOS range and now displays all of key shooting and user interface information along with image playback. The AF system expands from 7 to 9-point, with a highly sensitive f/2.8 center point for exceptional performance in low light. Even with the image resolution increase, maximum frame burst almost doubles from 14 to 27 large JPEGs and from 5 to 10 RAW.

Dust reduction

The EOS 400D is the first camera to incorporate the EOS Integrated Cleaning System. Based on significant research into the causes of dust in D-SLR cameras, the system combats dust in three important ways: Reduce, Repel and Remove.

Reduce - Internal camera mechanisms are designed to minimise dust generation. The body cap is redesigned to prevent dust generation through wear on the cap itself.

Repel - Anti-static technologies are applied to the low-pass filter covering the front of the sensor so as not to attract dust.

Remove - A Self-Cleaning Sensor Unit uses hi-frequency vibrations to shake dust from the low pass filter for a period of approximately one second after each start up. For instant shooting after power up, this feature is disabled immediately the shutter release is depressed.

Canon has also developed an internal Dust Delete Data system, which can map the position of any visible dust on the sensor. This can then be deleted automatically after the shoot with the latest Digital Photo Professional software.

The EOS advantage

The EOS 400D inherits a number of advanced features proven in higher-end EOS models, such as the EOS 30D and 5D. These include its 9-point AF system, Picture Style, 9,999 image capacity folders and expanded Pictbridge functionality.

The EOS 400D also incorporates the same DIGIC II processor found across the EOS range right through to EOS‑1 professional models. As well as providing superior image quality through advanced rendering algorithms and almost instant 0.2 second start up time, DIGIC II’s accelerated processing prioritises the photographer’s ability to keep shooting by clearing the buffer quickly between frame bursts.

Upgrading

The upgrade path to the EOS 400D from earlier EOS models is made easy by maintaining the same intuitive user interface and basic layout of key features and functions. Photographers are also able to use the same battery and Battery Grip BG-E3 as used on the EOS 350D, as well as continued support for all EF and EF-S lenses, EX Speedlites and EOS accessories.

Software

Consistent with the entire EOS Digital range, the EOS 400D is supplied with a comprehensive software suite to help the photographer’s workflow. This includes Digital Photo Professional (DPP), a powerful RAW converter that provides 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 Capture, Image/Zoom Browser and Photostitch, plus 100MB of personal online space on CANON iMAGE GATEWAY, Canon’s online photo sharing service.

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.
