The Canon EOS 1D Mark IV offers advanced photographic and video imaging possibilities for demanding professionals. Boasting a 16.1 Megapixel APS-H sized sensor, Dual DIGIC 4 Image Processors, and a completely redesigned 45-point AF system, the 1D Mark IV builds upon the success of the legendary 1D series with expanded ISO performance (up to ISO 102,400), HD video recording, and 10 frames-per-second continuous shooting.
The 1D Mark IV's all new autofocus system employs 45 AF points, 39 of which are cross-type. All focus points can be selected automatically or manually, and programmed for priority based on the portrait or landscape orientation of the camera. New AI Servo II AF uses advanced algorithms to track moving subjects with precision and accuracy, even under the most difficult shooting conditions. An improved 63-zone metering system analyzes the frame for optimal exposure.
True 1080p HD video can be recorded at 24 (23.976), 25, or 30 (29.97) frames per second for better compatibility with non-linear editing systems. 720p HD and 640 x 480 SD video are captured at 50 or 60 (59.94) frames per second, offering the smoothest method of recording action subjects. An integrated mono microphone records spontaneous audio with video, while a 3.5mm stereo input offers higher quality options for professional applications.
Additional features include environmentally sealed magnesium-alloy construction, integrated sensor cleaning, and a 300,000 exposure shutter rating. With all this and more, the Canon EOS 1D Mark IV represents a complete photo and video solution for professional photographers and filmmakers.
When shooting HD video in AE modes, the EOS-1D Mark IV employs Center Weighted average metering to help ensure stable motion-picture exposure with the camera automatically selecting the ISO speed, shutter and aperture. Full manual exposure control is also available while shooting video when the camera is set to Manual mode.
Video can be captured at 1920 x 1080 resolution at frame rates of 24 (23.976), 25 or 30 (29.97) frames per second, for up to 4GB per clip. Movies are saved as MOV files and can be viewed in Full HD with HDMI output. Other recording sizes include HD at 1280 x 720 (50/60 (59.94) fps) or SD/VGA at 640 x 480 (50/60 (59.94) fps). The EOS-1D Mark IV has a built-in microphone for simple mono recording and stereo sound can be recorded through a self-powered external microphone.
