The EOS 5D is a 12.8 megapixel digital single-lens reflex (DSLR) camera body produced by Canon. The EOS 5D was announced by Canon on August 22, 2005, and at the time was priced above the EOS 20D but below the EOS-1D Mark II and EOS-1Ds Mark II in Canon's EOS digital SLR series. The camera accepts EF lens mount lenses, although third party manual lenses in conjunction with an adapter can be used on the camera, though without the use of autofocus.

The EOS 5D is notable for being the first full-frame DSLR camera with a standard body size (as opposed to the taller, double-grip "professional" camera body style). It is also notable for its price, introduced at just over $3000 USD or £2000 GBP, which set a significant new low price point for full-frame DSLRs; its only full-frame competition at the time was the Canon 1Ds Mark II, which cost more than twice as much.

On September 17th, 2008, Canon announced the camera's successor - the Canon EOS 5D Mark II.^[2]

[edit] Features

[edit] Sensor and Image Processing

The 5D has a 35.8 x 23.9 mm full-frame CMOS sensor with 13.3 million pixels (12.7 megapixel effective). The very low pixel density of only 1.5 megapixels per square centimetre, combined with the redesigned DIGIC II image processor, provided significantly lower noise at all ISO sensitivities than any other consumer camera on the market. This position was only challenged by the release of the Nikon D700 nearly three years later. ISO speeds from 100 to 1600 are provided, adjustable in 1/3 steps (ISO can be expanded to L: 50 or H: 3200 with a menu function).

[edit] Autofocus and Metering

The 5D has 9 autofocus points (plus 6 "invisible assist AF points" available only during continuous-focus tracking) arranged in a horizontal diamond pattern. The AF system was a minor upgrade to the one on the 20D, and was not up to the standard of the professional 1D series. The camera used TTL 35 zone SPC metering with four variations (evaluative, center-weighted, partial, spot) and exposure compensation of -2 EV to +2 EV in steps of 1/3 EV. E-TTL II flash metering is provided.

[edit] Shutter

The shutter was rated to 100,000 shots, and capable of speeds up to 1/8000 s with a flash sync speed of 1/200 sec.

[edit] Ergonomics

The 5D was very similar in design to the popular 20D, and most of the controls were identical or nearly so. Differences included:

A much larger and brighter pentaprism viewfinder with approx. 96% coverage. This arrangement, borrowed from the 1D range, eschews the pop-up flash of the consumer range.
A larger 230,000 pixel, 2.5" (63 mm) colour TFT liquid-crystal monitor

[edit] Speed

Although the 5D offered only 3 frames per second continuous shooting the improved buffer throughput allowed up to 60 frames in large JPEG mode, and up to 17 frames in RAW, a significant improvement on earlier models.

[edit] Physical Dimensions

Size (WxHxD): 152 x 113 x 75 mm (6.0 x 4.4 x 2.9 in)
Weight (body only w/battery): 895 g

[edit] Accessories

An optional BG-E4 battery grip, which provides an additional shutter release and control wheel for additional comfort and stability when shooting in portrait mode, was released at the same time. The grip can hold two standard Li-Ion batteries or 6x AA-size cells. When mounted, the size of the 5D is comparable to the professional 1D series of camera bodies.
