A possibly naive question from a digital newbie: After 40 years with a film SLR, I recently bought my first digital camera - an OMD EM1. I initially thought I would buy a set of lenses equivalent to my film set (35mm, 85 and 135 or 200). I started with the Oly 45mm and planned to get the 75mm later. After 6 months with the 45, I'm wondering if i need another telephoto at all. Why not just crop after the fact? I've done test prints at 6X magnification and the sharpness is amazing. With image stabilization & autofocus, the human error is pretty much gone, leaving only a very sharp image. I can certainly print a 2x crop at 11x14, which is the most I want to do. Shooting 35 mm slides, I had to compose the picture perfectly in the viewfinder so I often needed a telephoto. But with digital, I can crop after the fact. The sharpness is fine and, if I know my theory correctly, I get the same perspective & depth of field from cropping that I would from a telephoto. So why would I put up with the expense, bulk and inconvenience of another lens? Am I missing something?
