I am one of them who are eager to see new 5D. Actually, the main reason to want full frame body is not only to get better image quality but also (rather) to get more useful lenses range. For example I don't like to use 70-200 on the crop body because its range starts from 110mm.
My question is how much full frame body has better IQ than the same mp crop body. If you use 12mp 5D and 12mp crop bodies(ex 450D), what kind of difference is between them in terms of image quality?
Sorry, if this question is old.
