Lentar Preset 135mm f3.5 m42 Screw Mount Prime Lens w/ Circ Aperture
This is an interesting lens that is perfect for you mirrorless vintage lens fans. It has a preset aperture and a million blades so the aperture is nearly circular.
The preset thing is cool too. It lets you dial in the aperture and then open or close it with a turn of the second ring. It has a universal T mount but it comes with an m42 mount attached.
This lens is in good condition with clean scratch-free glass and smooth focusing.
Caps and the leather case are included.
