Autofocus and metering
The 7D has 19 autofocus points arranged in a horizontal diamond pattern. The AF system is a new design which uses a translucent LCD display in the viewfinder. The camera uses TTL 63 zone color sensitive metering system with four variations (evaluative, center-weighted, partial, spot) and exposure compensation of −3 EV to +3 EV in steps of 1/3 EV.E-TTL II flash metering is provided. The translucent LCD can also display guide lines and the spot metering area circle. As with most other video-capable DSLRs, the Canon EOS 7D’s autofocusing function does not work while recording video. Instead, you can only trigger a contrast-detect AF cycle before recording process by hitting the AF button on the camera’s rear panel. You can manually focus the lens during a recording.
The shutter is rated to 150,000 shots, and is capable of speeds up to 1/8000 sec, with a flash sync speed of 1/250 sec.
The 7D has roughly the same dimension as the 5D Mark II, with the button layout having gone through an update. It also features a 100% viewfinder with 1x magnification.
The 7D was the first Canon camera with a dedicated movie mode switch, the preceding 5D Mark II and 500D movie recording being done in live view.
The dual Digic IV processors let the 7D reach 8 frames per second continuous shooting; the buffer throughput allows up to 94 frames in large JPEG mode, and up to 15 frames in RAW.
