I am looking into Macro photography and I am looking at two Nikon lenses for my Nikon D700. This will mainly be for personal use as photography is mainly a hobby for me. The lenses are the 60mm f/2.8 & 105mm f/2.8 both having auto focus but the 105mm offers VRII. For outdoor use I favor the 105mm but just posting this for other peoples views and do any of you use ext. tubes?
