made by Canon. It was announced on September 1, 2009. Its particularly notable features are its 8.0 frames per second continuous shooting, 19 point auto-focus system, movie mode, and built-in Speedlite transmitter.
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.
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.
