LogoCanon EOS ( Electro-Optical System) is an (SLR) and mirrorless camera series produced by Introduced in 1987 with the, all EOS cameras used until October 1996 when the was released using the new and short-lived film. In 2000, the was announced, as the first designed and produced entirely by Canon.
Since 2005, all newly announced EOS cameras have used digital rather than film. The EOS line is still in production as Canon's current (DSLR) range, and, with the 2012 introduction of the, Canon's (MILC) system.The 'EOS' was chosen for, the goddess of the in, and is often pronounced as a word ( ), although some spell out the letters, reading it as an.The EOS emblem was created using typography.It competes primarily with the series and its successors, as well as autofocus SLR systems from, /, and /.At the heart of the system is the, which replaced the previous, which mainly supported only manual-focus lenses.
Features of EF-lensThe bayonet-style EF lens mount is at the centre of the EOS camera system. Breaking compatibility with the earlier, 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 similar in some ways to Canon's earlier attempt at AF with the.
Other manufacturers including (with its G series of interchangeable-lens 35 mm rangefinder cameras), 's 1983 F3AF, and (with its ) have since embraced this type of direct drive system. It is a large lens mount compared to most of its competition, enabling the use of larger aperture lenses. EOS flash system. A, an early E-TTL flash from 1998The 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 manual-focus camera, the, launched in 1986. This was the first Canon camera with (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.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 system to judge where the main subject was for more accurate exposure.
E-TTL II, which was an enhancement in the camera's only, replaced E-TTL from 2004.Canon -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. Canon also produces Speedlite accessories, including the OC-E3 Off-Camera Shoe Cord, which can be used to hand-hold the flash while allowing the camera to control it through the cord. The Off-Camera Shoe Cord is popular among portrait photographers who need to have more control over lighting than a camera mounted flash can offer.EOS cameras As of 2017, Canon has released no fewer than 70 EOS SLR and DSLR camera models, starting with the introduction of the EOS 650 in 1987.
In the 1990s, Canon worked with Kodak to produce digital camera bodies, starting with the EOS DCS 3 in 1995. The first digital EOS SLR camera wholly designed and manufactured by Canon was the, released in 2000.Canon sold two EOS cameras designed to use the film format, the and the.Canon also sold a manual-focus camera, the, which used the same EF lens mount as the EOS cameras.
It came with all the automatic and manual exposure functions but lacked autofocus. It came equipped with a split-screen/microprism for precise manual focusing. Canon EOS M, Canon's first mirrorless system cameraEye-controlled focusing Through the tracking of eyeball movements, EOS cameras equipped with eye-controlled focusing (ECF) (some identifiable by the suffix E) were able to select the desired autofocus point in the scene, based on where the user was looking in the viewfinder frame.
ECF was especially useful in sports photography where the subject may shift its position in the frame rapidly.EOS cameras equipped with ECF were the (U.S. Model names are shown; see the table below for equivalents in other countries), EOS Elan IIE, EOS IXe, and.Canon did not continue its use of eye-controlled focusing in its digital SLRs. The EOS Elan 7NE was the last EOS camera to have this function.Quick control dial.
Rear view of Canon 60D featuring quick control dial to the right of the LCD screen.Most prosumer and professional level EOS cameras feature a large quick control dial (QCD) on the camera back. The first consumer-level EOS camera with this feature was the, announced in February 2015. This feature allows easy adjustment of certain parameters using the thumb. The QCD is used for quick access to often-used functions that would otherwise require a more complicated procedure of button presses and dial clicks.
Settings such as ISO button, Exposure Compensation button, or menus are all easily available through the QCD.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.A QCD is programmed to do perform useful functions, which may 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 Currently, top-line EOS cameras have either 61 or 65 user-selectable autofocus (AF) points. Autofocus is a camera's ability to focus a lens automatically on an object by pressing down on the shutter button. Autofocus most often chooses the closest image in the field of view to focus on. The following EOS cameras feature such a system, with 61 points unless otherwise indicated:.
The, introduced in March 2012. The, announced in October 2011 and originally scheduled for sale in April 2012, but delayed until June 2012. Since replaced by a Mark II version.
The, on sale since November 2014. Canon EOS DCS 3cPrior to the introduction of the EOS D30 digital SLR, produced four digital SLRs also sold under the Canon brand. These cameras used a with the image sensor and associated electronics designed and built by Kodak together with modified internals of the EOS-1N film SLR.
Due to using the Canon EOS body, these four digital SLRs can accept EF lenses. The four cameras were:ModelRelease dateJuly 1995December 1995March 1998December 1998After termination of the agreement by Canon, Kodak cooperated with – who at that time had a Canon license – to produce the based on a SA9 SLR body in 2004, which was compatible with EF lenses.The following digital SLRs, starting from the D30, had bodies and sensors completely designed and manufactured by Canon (except for the Canon EOS-1D, which uses a Panasonic sourced CCD sensor).Canon digital SLRs are equipped with a sensor (with the exception of EOS-1D that uses a sensor). Canon designs and manufactures their own CMOS sensors.See also Canon., a derivative of the EF mount designed for DSLRs with APS-C sensors., a derivative of the EF mount designed for MILCs with APS-C sensorsSingle lens reflex.References.

Canon themselves might be able to tell you. Send them an email directly.Canon techs do drop in here on the forum occasionally. But mostly it's just folks who shoot with Canon gear, who are active here. So if you want a more precise answer, I'd suggest contacting them directly via email.You can get at least the date that camera models were introduced off the Canon Museum website.DSLRs:Compact Digital:Film cameras:If you know the model that replaced any particular camera (such as that a 50D replaced 40D, and a 60D replaced 50D, etc.) you also can estimate the end date of a particular model at the museum website.
