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 other consumer cameras on the market at the time.[citation needed] 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). The ISO 50 setting reduces dynamic range by a stop in the highlights.[5]
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.[citation needed] The camera uses 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.
Shutter
The shutter is rated to 100,000 shots,[6] and is capable of speeds up to 1/8000 sec, with a flash sync speed of 1/200 sec.
Ergonomics
The 5D is very similar in design to the 20D, and most of the controls are identical or nearly so. Differences include:
- 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
Speed
The 5D can shoot up to 3 frames per second, with a buffer that can store up to 60 frames in large JPEG mode, and up to 17 frames in RAW.
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
File numbering
The 5D is the first prosumer Canon DSLR where 9,999 images are stored to one folder (which was exclusive to the EOS-1D series), unlike its predecessors where 100 images are stored
