It seems to me that this is not only a problem of this particular lens but that the entire lens mount is flawed because of the very small flange back distance.

Then why can you get better results with a 5N? They just need to take care with the sensor design, and things work out ok. The short flange distance is a plus, it keeps the camera body compact, wider angle lenses compact and offers a lot of possibilities adapting different mounts including M39 screw mount and M-mount.
