nikon on nikon?
I recently got a nice used nikon f3 with a 50mm lens. (I'm woefully underinformed about lenses, as you may realize as you read this.) Anyway, it was suggested to me to find zoom lens with a built-in macro. In particular, I've been offered a used Vivitar nikon-mount used lens 70-200 mm with macro for $85 from a reliable local repair shop.
--does this sort of lens configuration make sense as an add-on to this camera--add telescopic plus close-up capability to the standard lens.
--are nikon lenses significantly better than the competition?
--where would I go looking for an equivalent nikon lens, if I decided on finding one?
