I have the original 5D, it's the best cheap way to get started with full frame. It has the crispiest 12 megapixels you will ever see with better resolving power than the 18mp rebel sensors no matter what lens. ISO quality is about the same as the rebels(may be a touch better) it only goes to ISO 3200. Hard to believe a 10 year old digital camera is so good. No features except what you need, it really is a digital camera for a photography purist.
