This sounds cool:
Capture images exactly as you see them
The Canon EOS 7D features an Intelligent Viewfinder that offers photographers 100 per cent frame coverage. With 1.0x magnification* - a first for EOS - photographers see a large bright image that helps to fully immerse them within the shot. A transmissive LCD incorporated in the viewfinder allows photographers to choose between various overlay features - such as AF points, the spot metering circle and composition grid – providing a range of tools that help when framing a shot. The EOS 7D is also the first EOS to introduce a Dual-Axis Electronic Level – in the viewfinder and on the LCD - that indicates both pitch and roll angles. This feature is particularly useful when shooting landscapes to ensure a level horizon, or when used in conjunction with a Tilt and Shift lens to level the camera.
