I look forward to using my 50mm 1.4 M42 lens on it too....though too bad it won't focus at infinity;
Good catch! Why won't your M42 lens focus to infinity? Overly thick adapter? If the lens focuses ok on an M42 body, then doesn't on the MX body, it's probably due to a poorly made adapter. The register distance is the same and the adapter should fit flush inside the camera lens flange.
