The EF lens mount

Main article: Canon EF lens mount

The bayonet-style EF lens mount is at the center of the EOS camera system. Breaking compatibility with the earlier FD mount, it was designed with no mechanical linkages between moving parts in the lens and in the camera. The aperture and focus are controlled via electrical contacts, with motors in the lens itself. This was a first for Canon, although other manufacturers including Contax (with its G series of interchangeable-lens 35 mm compact cameras) and Olympus (with its Four Thirds digital SLR system) have followed Canon's lead.

EOS flash system

Main article: Canon EOS flash system

The flash system in the EOS cameras has gone through a number of evolutions since its first implementation. The basic EOS flash system was actually developed not for the first EOS camera, but rather for the last high-end FD-mount manual-focus camera, the T90, launched in 1986. This was the first Canon camera with through-the-lens (TTL) flash metering, although other brands had been metering that way for some time. It also introduced the A-TTL (Advanced TTL) system for better flash exposure in program mode, using infrared preflashes to gauge subject distance. The Canon EOS flash system has gone a long way since the basic TTL (Through-the-lens) flash metering system. ... Running water frozen by flash. ...

Through-the-lens (TTL) metering is a photographic technique in which measurements (usually of light levels) are made through the lens of a camera. ...

This system was carried over into the early EOS cameras wholesale. A-TTL largely fell out of favor, and was replaced by E-TTL (Evaluative TTL). This used a pre-flash for advanced metering, and used the autofocus system to judge where the main subject was for more accurate exposure. E-TTL II, which was an enhancement in the camera's firmware only, replaced E-TTL from 2004. In computing, firmware is software that is embedded in a hardware device. ...

Canon Speedlite-brand flashes have evolved alongside the cameras. They are capable of wired and wireless multi-flash setups, the latter using visible or infrared pulses to synchronise. Speedlite is the brand name used by Canon Inc. ...

EOS cameras

As of 2005, Canon has released no fewer than 40 EOS SLR camera models, starting with the introduction of the EOS 650 in 1987. The Canon EOS series ushered in the digital age with the EOS DCS 3 in 1995, although it was a joint collaborative effort with Kodak. The first digital EOS SLR camera wholly designed and manufactured by Canon is the EOS D30, released in 2000. 2005 is a common year starting on Saturday of the Gregorian calendar. ... Eastman Kodak Company (NYSE: EK) is a large multinational public company producing photographic equipment. ...

Canon has also released two EOS cameras designed to use the APS film format, the EOS IX and the EOS IX Lite. An Advanced Photo System (IX240) film cartridge Advanced Photo System (APS) is a film format for still photography. ...

There is also a manual-focus EOS camera, the EOS EF-M. It comes with all the automatic and manual exposure functions but lacks autofocus. However, it comes equipped with a split-screen/microprism focusing screen for precise manual focusing.

Eye-controlled focusing

Through the tracking of eyeball movements, EOS cameras equipped with eye-controlled focusing (ECF) are able to choose the appropriate autofocus point based on where the user is looking in the viewfinder frame. ECF comes especially useful in sports photography where the subject may shift its position in the frame rapidly.

ECF is a function that is usually loved or hated. Some users feel that it is not reliable enough for common use. Others report that they are able to use it reliably. Much of this depends on the user. Eyeglasses can also reduce its accuracy for some.

EOS cameras equipped with ECF are the EOS A2E (U.S. model names are shown; see the table below for equivalents in other countries), EOS Elan IIE, EOS 3, EOS Elan 7E, and EOS Elan 7NE.

Quick control dial

An ergonomic design, most prosumer and professional level EOS cameras feature a large quick control dial (QCD) on the camera back. Allowing easy operation of the camera using the thumb, the QCD is used for quick access to often-used functions that may otherwise require a more complicated procedure of button-presses and dial-clicks.

Cameras equipped with the QCD can easily be operated with one hand (forefinger on the main dial, thumb on the QCD) without taking the eye off the viewfinder.

Some useful functions that a QCD is programmed to do include setting exposure compensation, setting of aperture in manual exposure mode and scrolling of images and menus in digital EOS cameras.

Multi-point autofocus system

The top-line EOS cameras have the most autofocus (AF) points (up to 45) in their classes, compared to cameras from other manufacturers. This increases the chances of a sharply-focused photograph in situations where the subject travels across the frame at high speeds, e.g. sports, birds.

Having so many AF points also helps relieve the photographer from having to use the 'lock focus and recompose' method of framing a photograph, since the subject will most probably have been picked up by one or more of the AF points. Even though the camera is intelligent enough to select the correct AF point(s) most of the time, EOS cameras equipped with a multi-point AF system will still allow the photographer to manually select an AF point.

EOS 3, EOS 1V, and the EOS 1D family feature a 45-point AF system, while most other EOS cameras in the last 3-5 years feature a seven-point AF system arranged in the shape of a cross. The EOS 20D features a unique nine-point AF system in a diamond-shape formation, and is the first EOS camera to feature this arrangement. The EOS 5D takes this 9-point AF system a step further by introducing six more 'invisible' AF points (i.e. not user-selectable) in helping the camera acquire focus faster during subject tracking.

Model naming scheme

Canon's naming scheme for its EOS cameras has been pretty haphazard, and thus it is not immediately obvious to a new EOS consumer the target market segment of a particular camera. The fact that a model is marketed with different names in different parts of the world adds to the confusion. For example, the EOS Rebel 2000 known in the Americas is also known as EOS Kiss III in Japan, and EOS 300 in other parts of the world. The Canon EOS 300 (also known as the EOS Rebel 2000[1]) is a single-lens reflex camera from Canons EOS series. ... The Canon EOS 300 (also known as the EOS Rebel 2000[1]) is a single-lens reflex camera from Canons EOS series. ... The Canon EOS 300 (also known as the EOS Rebel 2000[1]) is a single-lens reflex camera from Canons EOS series. ...

Despite the naming confusion, there is a general guideline to help consumers identify which market segment a particular EOS is targeted at.

There exists an "advanced prosumer" line of EOS A2 (EOS 5) and EOS 3 sharing many features of the EOS 1-series cameras, but is priced more modestly compared to the 1-series, presumably to attract professionals and alikes that do not require the same performance and ruggedness of the EOS 1-series cameras.

Digital cameras

Prior to the introduction of the EOS D30 digital SLR, Canon in collaboration with Kodak produced four digital SLRs by modifying the internals of the EOS-1N film SLR. These four digital SLRs had a Canon EOS body and thus can accept EF lenses, while the image sensor and electronics were designed and built by Kodak. The four cameras were: Eastman Kodak Company (NYSE: EK) is a large multinational public company producing photographic equipment. ...
