The pictures come out clear because of diffrent lense style and pixel sizes.... Bigger pixel cameras can take pictures that can be made larger without distortion... It all relates to the actual amount of pixels in a certain area. Certain camera's have diffrent settings for speed and action shots, however with digital camera's in order to get the same quality photo has a classic film photo it take alot of money, then again the regular style film camera's arent really cheap either. The newer more expenzive camera's will do anything your average photo taker would ever need, in fact anything about about 4.0 pixles will print good 4x5 pictures but if you plan on making them larger your going to need more pixels.
