K&F Concept M42 to Micro Four Thirds Lens Mount Adapter

This is a K&F Concept adapter that lets you use M42 screw mount lenses on Micro Four Thirds cameras. Works great if you want to try out some vintage glass on your digital m4/3 camera like the famous Helios 44-2 58mm lens. Completely mechanical, no moving parts, no glass, no chips. Just a hunk of metal to reliably adapt an old m42 lens to a digital camera. It's in good shape, I just don't shoot micro four thirds anymore.
