I am a professional wedding photographer, so I'm always looking for the best! My main camera used to be the Canon EOS-20D, but since I got the Canon EOS-5D, I would never go back! It is such an improvement from the other EOS cameras, you can see the difference so easily comparing pictures. The sensor is very high quality, and the colors in all the pictures are so vibrant! I rarely have to use a computer program to adjust my pictures because the 5D does everything for me in the taking! Also, the sensor is a full-frame sensor, which means you get wide-angle pictures without having to use a wide-angle...
