I want to preface this by saying YES I have searched Google and I do know all of the technical specifications and features of the respective cameras I am looking at. I am merely seeking advice as to which suits me best. I recently sold my XSi. I was happy with the picture quality but found myself running into many issues with the buffer size as well as the build quality (I started bringing it everywhere and it was taking a beating). I shoot mostly athletics, low light (starry) landscapes and people. I am not paid for my work but enjoy making prints as gifts and art for around my home. I have a nice Tamron 28-75 f/2.8 that I plan on keeping. I also plan on getting a Canon 50 f/1.4 (or sigma) as well as a Canon 15 f/2.8 Fisheye. (obviously not included in my $1300 budget) I have narrowed it down to these three cameras: Canon 1d Mark II (used) Pros: The high FPS I'm looking for, the full frame sensor, the amazing build quality. Cons: upper end of my price range (I found one for 1299, but would still need to buy a CF card) heavierish use Going to be at the high end of my price range. Canon 5d Mark I (used) Pros: Every example shot I see of this body is absolutely stunning, everyone calls it the gold standard. Good build quality. Cons: Slow. Canon 50D (new) Pros: Fast, found a "like new" one locally for $1000 which is nice, solidly built. Latest and greatest (for the time being) Cons: I would really like to get into FF for landscapes and portraits. Do what you do best and give me some advice!
