Canon EOS 1D Mark IV to the floor with 1080p video

Canon has busted out the EOS 1D Mark IV professional dSLR. The successor to the Canon EOS-1Ds Mark III is strutting a 16-megapixel sensor and shoots 1080p high-definition video.

The APS-H CMOS sensor, Dual DIGIC 4 processors and 14-bit colour conversion allow the Mark IV to shoot up to 10 frames per second at full resolution, for up to 121 JPEGs or 28 raw files.

Video is shot at 1080p full high-definition video at 30, 25 and 24fps. 720p footage is captured at 60 and 50fps. There's a dedicated video button and mini-HDMI connection.

Canon's highest ISO range weighs in with sensitivity from 100-12,800, and extended range from ISO 50 to 102,400. That's on a par with the Nikon D3S announced last week, but again we'll be interested to see what the results actually look like, and whether they're ruined by noise.

The Mark IV offers 45 autofocus points, with 39 f/2.8 sensitive cross-type points. All 45 AF points are user-selectable and are designed so those points at the edge of the frame give the same sensitivity as those in the centre. The camera tracks and stays focused on moving objects with a new AI Servo II AF system, even in burst mode, with AF controlled by a dedicated microprocessor. You can pick a more precise focus area with the new Spot AF function, when shooting with lenses that have an AF Stop button.

You can also save different focus points to be selected at the press of a button, or selected depending on the orientation of the camera. The metering system packs 63 zones and a dedicated sensor.
