I'am about to shoot a short, and planning on renting a set of zeiss cp2 lenses. One thing is still not very clear to me, even though I scanned the internet for examples and reviews, I just can't find any examples of cp2's on a t3i or a t2i. Full of them on the 5D but I can't really consider it as a benchmark, since the 5D is a full sensor, and mine is not. I just want to know how much of a difference they will make in sharpness and "better quality" of my image(not the look and feeling), compared to lenses I own myself ( Canon 50mm 1.4, Tokina 11-16mm 2.8, etc, mostly the cheaper lenses on the market). Any info would be nice.
