Canon EOS 7D

Top features include 8 fps continuous shooting and Full HD video

The Canon EOS 7D’s AF system allows numerous AF area selection modes never seen before in an EOS SLR camera. New modes include:

· Spot AF mode reduces the size of a single AF point to focus on small subjects like an animal in a cage.
· AF Point Expansion mode uses a cluster of AF points adjacent to the selected AF point to automatically assist focusing on moving subjects, such as an athlete on the run.
· Zone AF divides the 19 AF points into five selectable focusing zones and makes it easier to achieve focus with subjects that are difficult to track with Single Point AF or AF point expansion, such as birds in flight.

Additional AF improvements include a revised Automatic AF point selection sequence that allows a user to pick any one of the 19 AF points as a starting point for tracking moving subjects in AI Servo mode. (Previous EOS models required the subject to first be acquired by the center focusing point.) If the subject moves away, the camera will continue to track the movement with the remaining points and display the active focusing point in the viewfinder. Also, a time-saving feature is AF Point Switching, which allows photographers to select and register one AF point for horizontal compositions and a second AF point for vertical shooting, ideal for studio and portrait photographers.

To complement the new AF system, the exposure metering system for the EOS 7D has been completely re-designed to take color information into account, another first for an EOS system. Canon’s iFCL metering includes a 63-zone dual-layer metering sensor that reads both illumination and color for consistent results in all lighting conditions, keeping exposure levels stable from shot to shot, even as the light source changes.

Canon’s new Intelligent Viewfinder uses a liquid crystal overlay to provide clear and precise displays of focusing points and zones, on-demand grid lines and a spot metering circle. The LCD overlay can also be illuminated in extreme low-light situations or turned off completely. The EOS 7D camera’s viewfinder includes a large all-glass pentaprism with an antireflective coating to maximize clarity and provide a brighter display. The EOS 7D’s Intelligent Viewfinder features 1.0x magnification with 100 percent coverage for accurate composition and checking of detail.

EOS HD Movie: Empowering the World of Videography
Canon has blazed new trails in HD video capture with the 5D Mark II. Now, the EOS 7D takes DSLR video to new heights with Full HD capture featuring fully manual exposure control, and selectable cinematic frame rates for both NTSC (National Television System Committee) and PAL (Phase Altering Line) standards. Compatible with more than 60 Canon EF and EF-S lenses, the EOS 7D lets videographers take full advantage of the camera’s large CMOS sensor to achieve the dramatic frame composition they desire. At the heart of the EOS 7D are two key proprietary Canon technologies, Dual DIGIC 4 Imaging Processors and a large APS-C–sized CMOS sensor, helping to render stunning color reproduction, amazing depth of field and fine detail, even in low-light conditions. The Canon EOS 7D allows for three video recording modes – Full HD and HD in a 16:9 aspect ratio and Standard Definition (SD) in a 4:3 aspect ratio, all at selectable frame rates. The EOS 7D Digital SLR camera will record Full HD at 1920 x 1080 pixels in selectable frame rates of 24p (23.976), 25p, or 30p (29.97); 720p HD recording at 50p or 60p (59.94) and SD video at frame rates of 50p or 60p (59.94). The EOS 7D features a new dedicated button to initiate live view for both video and still shooting. Once engaged, the same dedicated button will start and stop video recording. Like the EOS 5D Mark II, the Canon EOS 7D Digital SLR camera provides users with the capability to use an external stereo microphone for professional audio effects or a built-in monaural microphone for convenience.

The Features You Asked For
A helpful new tool for architectural and landscape photography where angles and perspective are critical is Canon’s new built-in Dual Axis Electronic Level, featuring an artificial horizon over the image on the rear LCD screen in Live View or in the viewfinder using illuminated AF points for easy leveling while shooting. The dual axis electronic level shows both horizontal roll and vertical pitch, making it easy to identify when the camera is in a fixed level shooting position and ready to take the shot.

The EOS 7D’s pop-up flash features a built-in Integrated Speedlite Transmitter for control of multiple off-camera EOS Speedlites without the need for an external transmitter. This built-in wireless option is a compact and economical solution for studio and wedding photography with multiple flash set-ups.
