Sigma 20mm f1.8 EX DG Aspherical - Lens

Autofocus wide angle lens made for Nikon F mount SLR cameras by Sigma. It has the AI ridge and AI-S indent but no bunny ear metering prongs so it will meter properly with all manual Nikon cameras (excluding the F, F2, and Nikkormats) and can be used with the advanced program modes of later models. It has a manual focus clutch and the autofocus requires a body with a built-in screw focus motor. Plastic/metal body available in black.
