Hello, I recently moved from film to digital (Canon 450D) and had some questions about the smaller sensor size. 1. Since the sensor is smaller it produces a larger depth of field, but do the lenses made for it compensate? Does a 50mm on a 35mm film camera give have roughly the same depth of field as my Canon 450D with a 50mm lens made for it? 2. If no, how much depth of field am I losing? A subjective answer if fine (e.g. a little, moderate, a lot, etc.) 3. I love shallow depth of field, am I screwed? I have two lenses currently that only go down to 4.5, but I haven't played with a faster lens yet. I want a 50mm prime that goes to 1.4, would I be happy with the DOF? Thanks, everybody!
