For improved image review and menu readability, the EOS-1D Mark II N is fitted with a larger, brighter 2.5" 230K pixel poly-silicon TFT LCD monitor, giving photographers a significantly larger viewing area. The improved screen has twice the number of backlighting LEDs so that its angle of view retains brightness and visibility both vertically and horizontally. This makes it easy to view images when camera is mounted in a fixed position. With image playback, the magnified view can be viewed straight away on any selected AF point and magnification is possible during the quick review immediately after image capture. The EOS-1D Mark II N is compatible with all Canon EF lenses and the entire EX series Speedlite flash range. Canon's E-TTL II flash system optimises flash exposures by linking distance information from the camera/lens system to the 21-zone evaluative or averaged metering readings from the pre-flash.The camera's focussing screens are interchangeable; an optional new "Super Precision Matte" Ec-S focussing screen enables easier manual focussing with fast lenses. Interfaces include video out (for display in both NTSC and PAL formats), IEEE1394 (Firewire) and USB.
