Maximum power of a lens

Web27 sep. 2015 · The way maximum magnification works in practice is that the closer you can get to the subject and still be able to focus the higher a lens' MM will be. An 800mm lens can make distant objects look much closer than they are. But because the minimum focus distance is around 20 feet, they only give a MM of 0.14X!
