As an aside to this topic, I often wonder if these minilabs and such do frequent calibration of their "lens" used to project the picture digitally onto the paper...lately I find my prints done at some labs to come back soft, yet I know darned well my lenses are razor sharp. This is the one nit I have with film in that there are too many "lenses" that can effect the final print: the cameras, and the enlargers, and perhaps the "lens" used to scan the negative for digital projection. At least with digital cameras, one only encounters one "lens".
