An 85mm lens on a 350D camera. It seems to me that many people think that you simply multiply the 85mm by the crop factor and you have a 136mm lens. Here's what I think - You don't! Instead of more you get less. Go out and take a photo on a full frame camera with the 85mm lens, print it say 16" x 10", cut 1.6 from the sides leaving the middle 10" X 6.25" of the original size and that's what you get, a cropped photo. ----------- | |-----| | | |1.6x | | | |-----| | ----------- [no expense spared graphic] Now if I had used a 136mm lens and would have been 1.6 times further back I would have got the same shot. At no time did the 85mm lens turn into a 136mm lens we just simply cut off the sides to give the same viewing angle.
