All tests were performed using the Mamiya focusing hood on an M adapter.

127 focused on closer subject via GG

RF images become misaligned, distance scale reads next-closest number

127 infinity focus through RF/VF

The lens seems to hit the infinity stop right before the RF images align. RF probably needs calibration. GG image is still out of focus. Pictured is the lens at the infinity stop.

75mm infinity focus

For the hell of it, I performed the same test with the 75mm. The RF is still probably slightly off, however the distance scale and GG image seem to correspond to each other.
