I know the Eos sports the full frame sensor, but I'm really trying to make the right choice through my technique. I've used Pentax in the past, looking for an upgrade, and with both of these bodies in my price range (and taking lenses into consideration), I'm interested in something that will suit my wildlife and landscape photographic needs, as well as freelance sports and odd studio work. I was leaning the D300 way, but now I'm second guessing. . . Objective/subjective thoughts?
