Let me rephrase the question: in 35mm format my favorite w/a is 24mm, not just because I like the FOV, but also because for me it's the widest lens that still looks "normal" - wider lenses seem to me to call attention to themselves as sort of "special effect" lenses. I think even in a rectilinear lens, there's a lot of keystoning, pincushion and various other linear alterations. Maybe "distortion" is the wrong word. So, on a 1.6 format camera, to get the same FOV as a 24mm I need to use a 15mm lens, but on a 35mm camera a 15mm lens is practically a fisheye. If I take a photo in 35mm with that lens and then crop it in PS by 1.6, those stretched lines are still evident. Therefore what I'm understanding - and help me out here - is that the same thing is going to happen on a 1.6 DSLR, that 15mm lens is still going to be a 15mm lens with all its innate characteristics, and the only way I'm going to get a photo similar to the one I take with a 24mm on my 35mm is with a FF DSLR. >>>> What you're referring to is "perspective distortion". This is caused by the relation/ratio of distances from objects to the lens, i.e. the magnification of near objects vs far objects. To make a close object appear the same size when using a wide angle lens as when using a longer lens, you need to be closer to it. However, the background is now proportionately farther away and is rendered at a much lower magnification, causing the distortion. The opposite type of perspective distortion is "telephoto compression", where shooting from far away make the relative magnification of widely spaced objects nearly the same. So in short, all that matters is angle of view and lens to object distances. If you were to take a picture of the same scene using 15mm and 24mm lenses _from_the_same_place_, a crop from the 15 would look just like the 24. N.B.
