Not sure that I even really want to do this yet. But the thought has been occurring to me. m4/3rds is still new for me. With each outing I'm getting to know my E-PL2 a little better. So maybe I should divert my up grade thoughts to lenses rather than actual camera bodies? I like to shoot animals, and this means I'm always after sharpness over all else. I like sharp fur and feathers.....and of course....eyes. So will a camera body upgrade improve this at all, or not? And would lens upgrading do more for my sharpness obcession, then newer bodies? I currently have only a 14-42 II, and a 40-150mm. Your thoughts on this would be of interest to me.
