Pentax K-mount to Pentax Q adapter

This adapter lets you use a Pentax K-mount lens with your Pentax Q.

If the lens has an aperture ring then you can control the aperture as normal by the ring.

If the lens does not have an aperture ring the aperture will be fully open when mounted on to this adapter. If you don't want full aperture you can adjust it by slightly turning the lens as if unmounting form the adpater. A few degrees will fully close the aperture.

The adapter does not have a locking pin for the lens but fits tightly enough to not need one. The lack of it also allows to change the aperture as described above.

The adapter does not have a tripod mount, something which I intend to do when I find some time for it.
