Jeff just made a comment that I didn't realize. Is it true that many more megapixels make up for some of the lost zoom in a camera? So I can crop and enlarge without losing detail? Would this require RAW photos? (I have no idea how to say this.) Also, would a large megapixel camera take better pics than a powerful zoom, because it would avoid the haziness that is unavoidable as a zoom pics up pollutants and other particles in the air?
So, would a 7 megapixel 3x zoom camera take equivalent cropped photos that a 3 megapixel, 12x zoom camera would take?
