There would be almost no noticeable difference between an 18 megapixel camera and a 20 megapixel camera. Personally, I would look for a camera with a fast shutter speed and a high Optical Zoom.
is a discontinued 6.3 megapixel digital single lens reflex (DSLR) camera.
The Canon EOS 40D is a 10.1 megapixel digital single lens reflex camera.
The Canon EOS 1D Mark III is a 21.1 megapixel digital single lens reflex camera, and is the first to break the 20 megapixel barrier.
