>>59600 Crop factor will affect the performance of the lens that you use. If a lens is your 50mm prime, then it will only work at 50mm for a film SLR. If you use a digital SLR with a crop factor, then multiply the crop factor by the length of the lens and you will have the effective length. So, your 50mm will work as a 75mm on a dSLR with 1.5x crop factor. It's very important to note this as 75mm is considerably longer than 50mm. This will also explain why your wide lens doens't feel that wide. It's because it isn't when on a digital body.
