I have a T2i myself that came with the 18-55mm kit lens. In a move toward a future 7D purchase, I got myself the EFS 17-55mm. Wow! What a difference.
In any case, this thread caught my attention because I was interested in shooting 2.35:1 and cropping in CS5, then the anamorphic option came up. Anything I do in the immediate future will be on the small screen, so I'm thinking that cropping is the obvious decision. If I'm understanding this correctly, I'm not altering the resolution, but just making the picture smaller in one direction.
