To whom it concern: after my various attemps to find a solution for duplicate dias with a slide duplicator and K1 ii, I think to have found a system.
This is because mi tubes don't communicate with K1; with all mine others Pentax there was no problem.
With a little piece of wood ( or plastic ) I block the lever tha that communicates with K1, this after put the ring at 13 for instance.
In this way tge diafghram of the lens remain at f 13 when you attack it to the camera and works in stop down.
If you, before to block the lever, use it at full aperture, you can find the best focus, that pratically remain always the same, then block and go in stop down.
Just a little complicated, but it works!
Best regards.
