It's not an issue now. Really! Imagine you are standing at a fixed spot, photographing a given subject. An 18mm on the *ist-D, a 28mm on a 35mm, or a 50mm on a 6x7 will produce images that are, as far as composition and framing are concerned, identical (except for the different aspect ratio of the 6x7, of course). If I showed you a small-ish print or image from each one (say a 3x5 print, or a 600x400 image) you would have no way of telling which came from which camera.
