M42 lens to Arri PL mount adapter

This is simple adapter allowing to use some of the Zenit/Praktica lenses on movie cameras with Arri PL mount. Due to flange focal distance differencies, it is necessary to recess m42 thread into the mount. That is why only narrow m42 lenses will fit it.

Inner diameter of the adapter is 53mm, depth is about 10mm. So, measure you lens(es) to see if it will fit BEFORE purchasing the adapter.
