[QUOTE="dck22, post: 508777, member: 41041"] I understand that compact DSLRs have a smaller sensor that full frame DSLRs and that a 50mm lens used on a sensor with a 1.5 crop factor would produce the same field of view as a 75mm lens (1.5x50) on a 35mm full frame sensor. What I cannot get my head around is lenses that are "optimized" for the smaller sensor like Nikon DX. Does a 50mm Nikon DX lens (optimized for small sensor) on a D5500 (small sensor) provide a 50mm field of view or a 75mm? What would the field of view be for a 50mm FX lens used on a D5500? I apologize in advance if everyone already understands this concept clearly, but I haven't found the answer in a format that makes sense to me. TIA [/QUOTE]
