Okay, here's what I understand. A 50 mm prime lens will shoot what looks most similar to the unaided eye. Most dSLRs (like theCanon Rebel) have an image sensor that is smaller than a 35mm film frame. Therefore, the 50 mm lens will produce an image that is "smaller" or "tighter" than a 35mm camera with a 50mm lens. It would be like looking at the same view, but through a smaller window. On such a dSLR, the resulting image will have the same view as an 80mm lens, but it will not be a telephoto or magnified image, it will just be tighter. Does a 50mm prime feel too tight for general shooting? Is a more wide angle lens more appropriate? As technology improves and becomes cheaper, will more camera maufacturers put full-frame sensors on amateur and "prosumer" range cameras?
