The M42 mount is older than retrofocus lenses, so particularly in the early CZJ period they were struggling to get the shorter focal lengths into the cameras. It may well be that CZJ presets of ~50mm or less might have been designed to fit as tightly to the small mirrors as they could manage, and in these cases a larger mirror from the later, wide-angle-is-easy era could be a problem. |
