Nikon Micro-Nikkor 55mm f/2.8 Ai-s with lens caps. For parts or repair. The glass has light haze and small fungus blooms which can be seen if you look closely with a light. It's clear to look through and doesn't seem to affect the photos, see the photos. The aperture ring turns smoothly but the lens does not stop down correctly...or at all. So yer shooting wide open, which is a look for sure. But take heart, these are some of the best lenses Nikon ever made and they can be fixed, and they work great on Nikon digital SLR cameras. 

The focusing barrel turns smoothly. The lens shows light handling wear.
