This is the excellent 105mm Micro lens from Nikon. It performs like the new version at half the price and gives 1:1 magnification without accessories. It is the "D" version (the photo cut it off).
It is in excellent condition with moderate wear and works perfectly. The glass is clean and scratch free and the mechanical action is very smooth. It comes with caps. This is a nice lens.
Note that this lens requires a body with the autofocus motor for autofocus operation.
