The Canon EOS 7D is an 18.0 effective megapixel APS-C crop CMOS digital single-lens reflex camera made by Canon.[2] It was announced on 1 September 2009 with a suggested retail price of US$1,699.[3][1] Its particularly notable features are HD video recording, its 8.0 frames per second continuous shooting, new viewfinder which offers 1.0X magnification and 100% coverage[4] 19 point auto-focus system, movie mode, and built-in Speedlite transmitter.[2]

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.[6]
Shutter
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.
Ergonomics
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.
Speed
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. But with UDMA CF-cards this can be increased somewhat (currently the fastest UDMA card has a 100MB/s write rate, Oct 2011).
Awards
The Canon EOS 7D won the 2010–2011 European Advanced SLR Camera[7] and the Technical Image Press Association Best DSLR Expert awards.[8]
Video
The Canon EOS 7D's video functions offers an unusually strong feature set that gives the photographer/videographer more control over the videos they create. The camera also offers the ability to record audio from an external source. Both shutter and aperture are available for manual control, and the 7D also provides multiple frame rate options, including three that match the HD television timing specs. Like most DSLR modes, the Canon 7D neglects endless autofocus during video recording, which is a great concern for advanced amateurs with pros likely to focus manually nonetheless. Separate movie clips that are captured by the Canon EOS 7D are limited to twelve minutes in the high definition 1080p and 720p modes, or 24 minutes in the standard definition VGA mode.[9]
The Canon 7D has acquired significance in the independent filmmaking world as an affordable alternative to digital cinema cameras. The camera was used on feature films, such as Black Swan[10] and Stanley Ka Dabba.[11]
