Canon EOS 5D vs 20D
With the announcement of the new full-frame, 12.8 megapixel Canon EOS 5D digital SLR a few days ago, Bob Atkins considers whether you should buy the new kid on the block or the cheaper EOS 20D.
“So the bottom line here is that if you’re an ultratelephoto fan and tend to shoot all your zoom lenses at maximum extension as well as hauling around the longest telephoto lens that you can afford and carry, then you may well be better off buying an EOS 20D than an EOS 5D. If you’re a midrange shooter with a fair selection of lenses, you’ll get higher technical quality images from an EOS 5D than an EOS 20D, though the extra $2000 you have to spend would buy you some pretty nice lenses. If you’re a dedicated wideangle shooter who can never get a wide enough lens, then the 5D will make you happier than the 20D.”

Don't forget the pixel size Bob! Quality pixel make for quality noise free images with good dynamic range and rich colors. I'm buying the 5D for those big pixels.

Er, Steamboat, I think you will find that a pixel is always the same size.

One pixel isn't even always one pixel (Fuji) Pixels are differnet in nearly every way between different sensors. Size, contruction, micro lens config, color filter pattern, noise characteristics and ccd vs CMOS just to scratch the surface. Check http://www.dpreview.com and compare a few different cameras with sensors from different manufacturers of just compare the pixel size on the Canon 20D and the Canon 5D. Pixel size is a factor of how many megapixels they fit into a certain size sensor. They are usually the same within a sensor company's generation of chips so they refer to each generation by pixel size and fit varying amounts of pixels into different physical sizes of sensors.

john - when talking about image capture, a pixel isn't always the same size: the area of the sensor that picks up "the pixel" can vary between cameras. Say you have a 8 megapixel APS-sized frame and an 8 megapixel full-sized frame - the pixels on the full-sized frame have to be larger.
Sure, on your screen in photoshop the pixel will look the same size. But the information that was captured will be different.

Stuart, exactly that was my point. There is a lot of variation in pixel sizes and even the same size pixels are not usually functional equivients because of differences in tech nology, construction and 10-20 other things if you start to really look into it.
