Developed incorporating feedback from professional photographers, theEOS-1D Mark IV features a new Canon 16.1MP APS-H CMOS sensor and a brand new 45-point Auto Focus (AF) system with 39 f/2.8 sensitive cross-type points, providing a wide selection of precise focus areas across the frame. Dual “DIGIC 4” processors provide the power to shoot continuous, high-resolution images at up to 10 frames per second (fps), as well as delivering the widest ISO range ever to feature in a Canon camera.
The combination of a custom-designed, high resolution 16.1MP APS-H CMOS sensor and Dual “DIGIC 4” processors ensures that detailed, crisp images are delivered at high speeds.
The inclusion of an APS-H sensor combines a high pixel-count with an effective field of view measuring 1.3x the focal length of the lens. This provides immediate benefits for sports, news and wildlife photojournalists, who operate on-the-move and need to get closer to their subjects and maintain fast apertures without resorting to longer focal-length lenses – which are typically heavier.
Continuous shooting is facilitated by the sensor’s eight-channel data read out, which provides a rapid read sequence and makes full use of the Dual “DIGIC 4” processors to enable high-speed 10fps shooting at full 16.1MP resolution, while maintaining image colours through 14-bit analogue to digital (A/D) conversion.
The ability to shoot images at 10fps, without any drop in resolution, means the EOS-1D Mark IV features the fastest continuous shooting with Auto Focus currently available from a Canon DSLR. The increased processing capacity of Dual “DIGIC 4” processors manages the increased data created by the 60 percent rise in image resolution, while still enabling the EOS-1D Mark IV to deliver a continuous burst of up to 121 large JPEGS, or 28 RAW images using a UDMA 6 card – ideal for fast-moving sporting action or news events where scenes are unfolding quickly.
The EOS-1D Mark IV also includes updated Picture Styles and the first ever integration of ALO (Auto Lighting Optimizer) in a professional EOS body, automatically correcting the contrast and brightness of images as they are recorded. These features combine to provide a faster workflow for those requiring press-ready images direct from the camera without the need for retouching, enabling photographers to concentrate solely on capturing that once-in-a-lifetime shot.
Full compatibility with the latest UDMA 6 standard Flash memory cards also ensures that image data is rapidly written to the EOS-1D Mark IV’s CF memory card. In addition, the flexibility to also record to a Secure Digital/SDHC memory card allows photographers to keep shooting for longer until they get the shot they need.
The EOS-1D Mark IV also delivers extreme low-light performance. Standard ISO on the EOS-1D Mark IV ranges from 100-12,800, while extended ISO ranges from a low of 50 to 102,400 – the highest ISO ever offered by a Canon SLR.This extreme low-light performance makes the EOS-1D Mark IV ideal for night shots or shooting at evening events, where the lack of light would normally make shooting impossible.
Intelligent noise reduction techniques keep chroma and luminance noise to a minimum, while maintaining colour balance, but never take control of the overall image quality away from the photographer. The architecture of the new 16.1MP APS-H CMOS sensor, featuring gapless microlenses with less surrounding circuitry and more sensitive, high-capacity photodiodes, also ensures that all available light is used as efficiently as possible to maximise ISO performance in low light conditions.
Light for its category, the EOS-1D Mark IV features a full magnesium alloy body, providing protection against knocks and bumps. The EOS-1D Mark IV has also been the subject of some subtle ergonomic redesigns, with the buttons reshaped and given a more defined ‘click’ when pressed, to make life easier for photographers operating in more extreme weather conditions where gloves may be necessary.
In addition to providing high-quality still image performance, the Canon EOS-1D Mark IV features EOS Movie function, providing the ability to capture 1080p High Definition (HD) video at 30, 25 and 24fps and 720p footage at 60 and 50fps.As well as complete compatibility with PAL, NTSC and native 1080/24p cinematic frame rates, the EOS-1D Mark IV offers full manual exposure, providing film makers and photographers with control over depth of field.
The EOS-1D Mark IV features a programmable button to enable quick movie shooting, allowing photographers to record HD video instantly at the touch of a single button. The EOS-1D Mark IV also features a mini HDMI output, enabling video and images to be viewed directly on compatible HD-ready TVs.
