A super-wide angle 20mm f/2.8 AIS lens for Nikon F Mount. Manual Focus. 

Excellent condition. This was my personal lens for years. It performs great! See above for an example. 

Condition is excellent. Smooth focus, snappy aperture, and clean glass. No dents or dings. Comes with front and back caps. 

Thanks for looking, and if you have any questions, please ask!
