M42 to EF Adapter, Manual Lens Mount Adapter for M42 42MM Screw Mount Lens Compatible with Canon EF EF-S EOS Cameras
SKU: KF06.148
Tremendous product. I was using my usual, cheaper, adapter for a newly purchased Takumar 50mm/1.4 and it tightened the lens up to the point where it was impossible to reach infinity and still move the f-stop. This adapter resolved the issue immediately, it felt like a much better fit and a much more professional product. The lens now moves freely and works perfectly - think I'll probably upgrade all my M42 adapted lens to this stirling effort.

A well made product. Easy to attach and works well. Very useful for using old style M42 screw thread lenses on modern cameras. Obviously wont work in most programme modes, but I found it is ideal in Manual and stopped down Aperture mode.

Excellent. Can reach infinity focus which I haven't been able to do with some other adapters.
