Canon EOS 7D Review

Canon EOS 7D Digital SLR Camera Body (18 MP, 3" LCD, Advanced Movie Mode, 8 fps, ISO 12800)
The Canon 7D is designed for speed, with dual DIGIC 4 chips to speed processing of these large 14-bit files, as well as keep up with the shutter's 8-frame-per-second top speed. Even the sensor had to be tweaked to enable such speed, with an 8-channel readout to more quickly draw the image off the sensor.
The Canon 7D's buffer can handle 94 JPEGs at top speed, or 15 RAW images.
For its part, the Canon 7D's shutter mechanism is rated at 150,000 cycles, and is the same design used by the 1D-series of Canon digital SLRs.
EV compensation has been expanded to five stops in either direction, and the ISO ranges from 100 to 6,400, with an expanded setting up to 12,800. The Canon 7D also sports an HD movie mode that will capture full HD at 30p.
The built-in flash has a wider range to handle up to 15mm wide-angle lenses, like the new EF-S 15-85mm f/3.5-5.6 IS USM, and the flash can also serve as the remote commander for up to three groups of flashes, another first for Canon.
Other new features include an electronic level, a RAW button, and a new Multi-function button for quick, programmable access to various functions. And don't forget the new 19-point autofocus system, complete with a new LCD viewfinder display overlay, obviating the need for interchangeable screens.
