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 −5 EV to +5 EV in steps of 1/3 EV (±3 EV visible in the viewfinder and top screen, ±5 EV visible on the back screen). 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, users can only trigger a contrast-detect AF cycle before recording process by hitting the AF button on the camera's rear panel. Users 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 older 5D Mark II with an updated button layout. It also features a 100% viewfinder with 1x magnification.
The 7D was the first Canon camera with a dedicated movie mode switch, instead of movie recording being done in live view as with the 5D Mark II and 500D.
The 7D has dual Digic IV processors and can reach 8 frames per second continuous shooting. When the camera was first released, the buffer throughput allowed up to 94 frames in large fine JPEG mode, and up to 15 frames in RAW. Firmware upgrades, most recently in August 2012 (see immediately below), have increased the maximum buffer size to 130 large fine JPEGs and 25 RAW files.
- Improved maximum burst for RAW images (up to 25)
- In-camera RAW image editing
- In-camera Image Rating
- In-camera JPEG resizing
- Maximum Auto ISO setting (ISO 400-6400)
- Manual audio level adjustment in movie recording
- Support for the Canon GP-E2 GPS unit
- File name customisation
- Time zone settings
- Faster scrolling of magnified images
- Quick control screen during playback
On 12 September 2012, Canon introduced the v2.0.3 firmware update with the following changes:
- Fix for a phenomenon in which the camera stops working when the auto power off setting takes effect
- Fix a phenomenon in which the maximum number of images that can be captured in a burst may be less than the actual number displayed in the viewfinder
- Corrections for some errors in the message displayed when saving RAW images developed in the camera
According to Canon's website, the EOS 7D model comes equipped with:
- EOS 7D Digital SLR Body
- Camera Cover R-F-3
- Wide Strap EW-EOS7D
- Battery Charger LC-E6
- Battery Pack LP-E6
- Stereo AV Cable AV-DC400ST
- Interface Cable IFC-200U
The Canon EOS 7D 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, depending on what Compact Flash Card is being used. Larger memory cards make for longer video lengths and are available in multiple sizes for the camera.
The Canon 7D has acquired significance in the independent filmmaking world as an affordable alternative to digital cinema cameras. The camera was used on the feature films Stanley Ka Dabba and Vazhakku Enn 18/9.
