Features[edit]
Autofocus and metering[edit]
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.

Shutter[edit]
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[edit]
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.
Speed[edit]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.
Firmware updates[edit]
On 6 August 2012, new firmware v2.0 was released
[7] with the following enhancements:
[8]
- 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:
[9]
- 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
On 2 December 2013, Canon introduced the v2.0.5 firmware update with the following changes:
[10]
- Fixes a phenomenon in which the image files cannot be transferred using the FTP protocol via USB cable after the Canon EOS 7D camera has established a wireless connection to the Wireless File Transmitter WFT-E5A.
