Itorex Pan-Focus Lens 50mm f40 for Nikon F brand_Kentmere 1/4" thread on the plateClearly not a low light lens, this Itorex 50mm f40 is a lot better than you'd expect: it's decently sharp at most distances, with a pretty good character, despite being a fixed focus single element lens. It's a T mount, which means it can be fitted to nearly any camera; it's provided here with a Nikon F mount.
