Canon lauched the professional photography market with 21 Megapixel, 5 Frame per second EOS-1Ds.

Key features

* 21 Megapixel full frame (35mm) CMOS sensor
* 5 fps continuous shooting for up to 56 frames
* Dual “DIGIC III” processors
* Highlight Tone Priority
* Auto focus system with 19 cross type sensors and 26 focus assist points
* EOS Integrated Cleaning System
* ISO 100-1600 (expandable to L:50 H:3200)
* 3.0” 230K pixel LCD with Live View mode
* Redesigned viewfinder now wider and brighte

Image quality

The EOS-1Ds Mark III produces files that exceed the standard resolution requirements of leading agencies and stock libraries. The third generation CMOS sensor incorporates a new pixel design with on-chip noise reduction circuitry to ensure high image quality all the way to ISO 1600. 14 bit A/D converters provide a total colour depth of 16,384 tones per pixel - delivering smoother gradations and more accurate colour reproduction.

The option to expand to H:3200 will be welcomed by professionals working in churches and sensitive situations where the use of flash is not permitted or desired. Where discretion is paramount, a silent drive mode delays shutter re-cocking for as long as the shutter release remains depressed.

Highlight Tone Priority mode gives wedding and landscape photographers the option to boost dynamic range for highlights when shooting above ISO 200 – reproducing more tonal detail from wedding dresses, clouds and other bright objects.
