One more example of Nikon AF Micro Nikkor 55mm F2.8 FX lens with caps . Focus works great, aperture opens and closes well and optics show light dust specs and Fungus traces inside plus usual wipe marks. Lens still takes decent pics. Lens barrel does show some wear. Above pics were taken with this lens on Nikon D90. This Lens will autofocus properly on the following cameras: Nikon D50,70,80,90,100,200,300,600,700,800,7100,7000,D3,D4 D750. On Entry level cameras like Nikon d40,40X,60,3000,3100,3200,5000,5100,5200,3300 etc you will have to focus manually.
