One more example of Nikon AF Micro Nikkor 105mm F2.8  FX lens with caps  . Focus works but at times struggles to catch the subject, aperture opens and closes well and optics show light dust specs and lot of Fungus traces inside plus usual wipe marks.  Lens still  takes decent pics. Lens barrel does show some wear. Above last three pics were taken with this lens on Nikon D90.

As is!
