This  Film SLR camera is a prince amongst cameras. One to have if you intend to be a photographer of note.

Canon EOS 1DS is compatible with EF/EF-S lenses and EX Speedlites. Canon EOS 1DS  has the 10.1 Mega pixel CMOS sensor which captures sufficient detail to make A4-size prints, even when editing your image. Canon’s CMOS sensor technology also ensures crisp, sharp images even in low-light conditions.
Canon EOS 1000D allows continuous shooting of large JPEG images at speeds of up to 3 frames per second, until the memory card is full. With a 2GB card, this lets you shoot up to 514 images without stopping.

7-point wide-area AF
A wide-area Auto Focus system on the Canon EOS 1DS , uses 7 separate focusing points to lock onto subjects fast. The central focus point enables focusing even under low-light or low-contrast conditions.

The Canon EOS 1DS  has a built-in dust prevention system , which guards images against the effects of dust in three ways: reducing dust generated inside the camera, shaking dust from the sensor each time the camera is turned on or off, and mapping stubborn dust spots for removal with the provided Digital Photo Professional software.
In Live View mode, use the bright 2.5” LCD to frame and take shots from awkward angles. During playback, the LCD provides detailed review of shots, and features a wide viewing angle which make it easy for many people to view together. Plus, it has a large, bright viewfinder, which allows framing of subjects even in the brightest conditions.
The Canon EOS 1DS , uses Canon’s cutting-edge DIGIC III processor  which produces rapid operation, accurate colour reproduction, fast start-up times, and low power consumption.
