Sorry if i'm going to ask a silly question... but i'm a bit curious about macro lenses.
I've seen lenses like 50mm macro, and then i've also seen lenses like 200mm macro.
I can understand if one has a 50mm macro to shoot something really close up and you move close to the object you are shooting. But 200mm macro - that i don't get. Is that to shoot something really far away e.g. a bird on a tree? But if that's the case, wouldn't a normal 200mm zoom lens be sufficient to just zoom and take the pic of the bird?
THanks in advice for all enlightenment on this.
