I've shot a lot of years with a Coolpix 8800, with a built-in 10x zoom, a prosumer camera with which I've gotten professional quality shots. My biggest complaint is the perspective distortion which I see on many shots. I can correct it many times in Photoshop, but there are times when adjusting one vertical pulls another out of alignment. I'm planning to buy the Canon 5D or its next iteration in the next few months. Will I see less of this distortion using a full-sized sensor, or is this distortion a problem of all digital cameras? Thanks.
