The Canon EOS-1Ds Mark III SLR Digital Camera (Body Only) incorporates a 21.1-megapixel full-frame CMOS image sensor that delivers astounding image quality, with 14-bit per-channel color, and utilizes the latest Dual "DIGIC III" Image Processors that work in tandem to speed up data handling and camera operation, while further refining imaging performance. The camera is constructed with a tough, high-durability body made from quality magnesium alloy, and a shutter that has been designed and tested to withstand over 300,000 exposures.
The Large three-inch LCD screen of the EOS-1Ds mark III provides broad color gamut and a wide viewing angle , and the Live View function uses the LCD display to provide an expanded and exceedingly convenient set of shooting options. By permitting the framing and capturing of subjects using the camera's LCD screen instead of the viewfinder, the shooter gains a 100 percent field view to more easily achieve the desired composition, and an added Custom Function allows auto-focus during Live View, and provides the user with the ability to magnify the image by five or ten times in order to ensure optimal focus. Live View is at its best during tripod shooting - particularly for close-up photography where precise focusing is imperative.
The EOS Integrated Cleaning System uses ultrasonic vibrations to literally shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. Users also have the option of engaging the "clean now" function at will or bypassing it altogether. Additionally, the manual sensor cleaning function raises the mirror and allows users to clean dust that has stuck to the low-pass filter. The second part of the cleaning system is a software solution that maps the location of any spots that may remain on the sensor. Subsequently, the offending dust information is subtracted from the final image during post processing using the supplied Digital Photo Professional software.
The EOS-1Ds Mark III Digital SLR is compatible with the full line-up of Canon EF lenses and is also compatible with any of the EX Speedlite line of flash units and supports the E-TTL II protocol that provides reliable flash output whether shooting fill-in flash pictures in sunlight, or using flash in total darkness. The camera is also compatible with 15 different interchangeable focusing screens, an extensive range of remote control and lighting accessories, and the WFT-E2A Wireless File Transmitter which permits wireless transfer and back-up, connection to a GPS receiver, or data transfer to a Hi-Speed USB 2.0 external storage devices as well as remote control of the camera in Live View mode.
