Helios 50mm f2 Helios-81 MC AI - Lens

Manual focus normal lens made for Nikon F-mount SLR cameras in the former Soviet Union. It has the AI ridge but no bunny ear metering prongs or AI-S indent so it will meter properly on most (excluding F, F2, and Nikkormat) manual Nikon cameras but cannot be used with the advanced program modes of later models. Metal body available in black.
