Again, We are discussing about venetting
not about whether a full frame will have a wide view than cropped one, this is a fact, nobody dispute that.
but the example I referred to:
http://www.dpreview.com/reviews/canoneos5d/page24.asp
showing 5D vs 20D using the same lens 24-70mm F2.8, and the venetting is so much worse on 5D than 20D.
Also it shows using 50mm F1.4, the same situation, 20D beat 5D hands down in terms of venetting.
