Excuse me if I am wrong, but after reading some advice on some of the forums on this site I feel the need to clear this up about the crop factor of of your camera and the relation to full frame and what impact a particular lens will have on a crop sensor. As we all know, 50mm on a full frame is exactly that 50mm,now put that lens on a crop sensor body and things change, it will now become 80mm lens on a 1.6x body. Some people have have the notion that you divide the crop factor buy the sensor size, but in fact you multiply it. Here is a guide for those of you that want to know what a given lens will do on a crop body I hope this will be helpful.
