I have purchased an ENSINOR 500mm f8 Mirror lens with M52 thread (pentax) fitting, to which I fitted a conversion ring to give me a K mount for my Samsung GX10 DSLR.
This combination did not immediately work, I had to put a thin washer between the lens and ring because the flange of the ring appeared (when tried alone on the camera) to sit too far into the camera body otherwise.
The lens now fits, however, the focus does not go to infinity! At the infinity setting on the lens, distant mountaintops are fuzzy.
Has anyone else had this problem and is there a cause/solution.
I do hope someone can help.
