tao said:who needs fullframe (unless if you are a wide angle NUT) when all you get are images with soft corners and exaggerated dust bunnies? go check out those 5D image samples on dpreview and you guys will know what I mean.
If you are referring to the bunnies on your censor, it doesn't matter which lens on your body. Consistently you get them the same size, shape and what have you. Its weird to see a lot of hammering on the wide angle pix posted by Canon, objectively speaking its a lens issue and not really a FF problem.
