There is a used 5d I on Craigslist for $900. There is also a 5d MK II for $1700. Both of these seem like good deals, and I'm wanting to jump over to full frame. I originally wanted to wait on the MK III to see what happens but it seems like that's just a waiting game via rumors. Anyways I shoot mainly weddings and portraits, and am wanting to get the 70-200 IS II to go along with whichever one I get. Please let me know your thoughts!!
