So I know I picked the two most random Canon bodies to compare but my dad is looking to get back into photography. He asked me about the t2i (which is about what he's willing to spend on a body). I have used the t2i and think it's great but here's the thing, he wants to essentially shoot landscapes exclusively. I thought he might benefit from a full frame, instead of a crop body, paired with a nice wide prime (or the 16-35 2.8 I'm about to buy - he's going with canon so he can borrow my lenses).
The only full frame that fits his price range will be a used 5D mark I. I've never had my hands on this camera though so I wanted y'alls opinions on the camera and if it's a safe bet to buy a used one. I'd love whatever help you can provide on the matter. Thanks.
