Hi All,

I joined the forum because I'm in need of some expert advice. Recently I've been putting some thought into upgrading from my current 450D to a full frame model. As I'm on a relatively tight budget I'm limited to second hand, and as I have a few lenses and a film body that I'd like to keep using I'm going to stick with Canon. That said, two camera that have caught my eye are the 5DMk1 and the 1D Mk2 as they both seem to go for around the same price on eBay and they both seem to have similarly good reviews.

I am aware that there 5D has a larger sensor than the 1D Mk2 but does that mean better IQ?
Can any body give me advice on which model I should go for? Or should I go for something else entirely?

Any help will be greatly appreciated.
