1DS Mark III, full-frame sensor, 21 Megapixel top quality camera. Launched in as 'the world's fastest D-SLR', the EOS-1D Mark III offered 10 megapixels at 10 fps (still one of the highest burst rates on the market). Rugged 1D series construction means this camera will work under most any conditions - heat, cold, vibration and high humidity. This particular one has been very well cared for. Still looks and works like new at a small fraction of the original price. Includes a genuine Canon battery and LC-E4 charger.
