It works very well when paired with my vintage Rikenon Panagor with Pentax K mount. Highly recommended especially because it is sold at a decidedly affordable price.

excellent product at a fair price, the diaphragm functionality is maintained even with Pentax DA lenses that do not have it even if you actually do not understand at what F you are shooting. Impeccable construction both on the camera side and on the lens side, one of the best adapter rings I have ever tried.

I bought this product because I already had other k&F concept adapters for Pentax K to M43, which I was satisfied with.
So I bought the adapter for Sony E for my son. Which now allows him to use his Pentax K lenses on his Sony A7 (operation verified with DA15, FA31 and FA77).
I took the model with ring which allows, by acting on the coupling lever of the mount, to adjust the diaphragm of his Pentax lenses without diaphragm ring (for example DA15, DA35, DA55-300), and is of course compatible with his lenses equipped with an diaphragm ring (FA31, FA77 and F135, M50 and M28).

The adapter is very high quality and connects easily to the camera and my analogue Agfa lenses. A (less high quality) plastic case is also included. Clearly recommended!
