Well I am just starting out in photography, and I'm looking to get the Nikon D40 with the 28-80 mm lens. Now I know this is probably a stupid question, but what kind of zoom will i get with a lens like that, I'm going to mostly be doing surf photography, so zoom and being tight on the subject is key. There is also a lens option of getting a 28-200mm lens. Would this be better? Please help out
