New Canon EOS 5D Mark II
Full-Frame D-SLR with 21.1 MP and HD Video CaptureHD and SD Video Capture
Canon has taken its expertise in imaging, photography and video capture technology to a new level with the EOS 5D Mark II Digital SLR. Answering the question of where SLR technology is going next, the EOS 5D Mark II features 16:9 Full HD video capture at 1920 x 1080 pixels and 30 fps as well as 4:3 standard TV quality (SD) video capture at 640 x 480 pixels and 30 fps, both capabilities appearing for the first time in a Canon SLR camera. Video capture is part of the camera’s Live View function, using the Picture Style that has been set for Live View still image shooting. This allows skilled photographers and cinematographers to adjust image sharpness, contrast, color saturation and white balance, and have those settings apply to the movie image. When recording video, the camera’s rear LCD screen can be letter-boxed by a semi-transparent border to match the aspect ratio of the movie recording size. Moreover, the EOS 5D Mark II camera’s HD video capability enables new levels of creative expression through its unfettered access to the complete line of more than 60 Canon EF lenses, which provide an incredible variety of visual effects including everything from ultra-wide-angle and fish-eye to macro and super-telephoto, including many large-aperture L-series professional lenses that can keep the main subject in razor-sharp focus while blurring the background beyond recognition.
The EOS 5D Mark II will record video up to 4GB per clip or a maximum continuous movie capture time of 29 minutes and 59 seconds, whichever comes first. Depending on the level of detail in the scene, a 4GB memory card can record approximately 12 minutes of video at full HD resolution or approximately 24 minutes in standard definition.[i]camera includes an HDMI (High-Definition Multimedia Interface) output to display crisp, clear images on a High-Definition TV. Video clips are recorded in .MOV format using an MPEG-4 video compression and sound is recorded using linear PCM[ii] without compression. The new camera features an input terminal for external stereo microphones as well as a built-in monaural microphone for convenience.

Live View Shooting
For both still images and video, the Canon EOS 5D Mark II camera features Live View, one of the most sought after features in digital SLRs today. The 5D Mark II features three Live View AF modes – Quick, Live and Face Detection Live mode – for capturing either still photos or video, each with its own attributes. Quick mode automatically sets One-Shot AF using the camera’s phase detection AF system. It also allows users to select the AF point, even while the Live View image is displayed. Although the camera’s reflex mirror must be lowered briefly to take an AF measurement in Quick mode, it is the fastest way to set focus automatically when the 5D Mark II camera is set for Live View.
Live mode uses contrast-detection AF with the image sensor and here, as with Quick mode, users can change the AF point using the Multi-controller. Face Detection Live mode uses contrast AF to recognize human faces. When multiple faces are detected, the largest face closest to the center of the frame is targeted as the AF point. While Live View is engaged users can still change settings including the AF mode (Quick, Live, Face Detection Live mode), drive mode, ISO speed, Picture style, White Balance, and more.
Peripheral Illumination Correction
The Canon EOS 5D Mark II Digital SLR camera automatically conducts peripheral illumination correction when shooting JPEG images, a function that previously could only be accomplished through post-image processing using software such as Canon’s Digital Photo Professional, which Canon supplies at no extra charge. Peripheral illumination correction evens brightness across the image field, making an image of a blue sky even toned throughout and reducing light fall-off at image edges. This new feature essentially eliminates one of the limitations of previous full-frame digital SLRs.
Auto Lighting Optimizer
Canon’s enhanced Auto Lighting Optimizer technology helps ensure each picture’s subject is clearly visible by analyzing image brightness and automatically adjusting dark areas in images so that they appear brighter. This function is ideal in high-contrast situations such as urban landscapes captured on sunny days, where the tops of buildings are brightly lit while street level details are obscured by heavy shadows. In this type of scene, the 5D Mark II camera’s Auto Lighting Optimizer technology preserves accurate exposure of the highlights while opening up the shadow areas for a more pleasing tonal rendition.
