Nikon 50mm f1.8D AF Nikkor brand_Kenko but be carefulThe Nikon 50mm f1. 8D AF Nikkor is a nice, compact standard lens for film and digital Nikon F mount SLRs. The autofocusing system in this lens requires an in camera focusing motor: it will mount to non motor SLRs like the 3000 and 5000 series, but it won't autofocus. In excellent condition, with clean glass and only very minor cosmetic wear.
