the lens forms the image and there are no better lenses than Nikon

if the close up feature on that lens is not enuff for you, then either buy the 60 mm Micro from Nikon, or get a used Nikon Micro

avoid using non-Nikon lenses on your camera; there have been a few over the years that have been as good as Nikon (Series 1) but you can sometimes even make money buying and selling Nikon lenses - that should tell you something

if macro photography is imp. to you then the spendy micro flash unit (replaces most of their old ring lights) is well worthwhile

to get even more involved Nikon makes some lenses with built in ringlights - right inside the lens - useful for dentistry and forensics, etc.
