What is a good macro lens to get for my Nikon D60?
I've been trying to find a good price, but do not know where to look, or what type to get. Also. Do you have to be an objective of the Nikon?
No, do not have to be an objective of the Nikon brand, but only a goal for Nikon. You can buy the Nikon or the lens manufacturers such as Zeiss, Sigma, Tamron, etc. Most of them are usually cheaper than the nikon models, but Zeiss and another company are expensive. Have you ever done a macro before? If not, I suggest buying macro (+ diopters) and macro testing filters. If you like macro, go ahead and buy a good macro lens. One of the low-cost models is even better than Nikkor counterpart Sigma Macro 105mm f/2.8 EX DG is. However in most cases other micro Nikkor are better than third party lenses are cheaper and better resale value too.
