I just spent a viel EOS (350D) to it, the range change is felt at the level of ergonomics. He would like under control. The goal is good, with this material, I managed quite difficult to take pictures in normal condition with telephoto lenses. The objective has a very good opening. I tried the 600D, it has the same ergonomics as the 350D but the 60D immediately had a better grip than the EOS series x00D. The "gadget" of the rotating screen is necessary to make some original shooting, I no longer have to lie down on the floor, or take a photo by diving to the blind, the rotating screen is a plus but the sight still remains the best choice. Moreover, the price difference between the 60D + 600D 18-138IS kit and kit + 18-135IS is really excessive.
