Excellent operation, very comfortable ring that allows you to close and open the membrane

It works very well in combination with my old Rikenon Panagor Panagor with Pentax K attachment. Highly recommended, especially as it is sold at a decidedly unreasonable price.

Outstanding product. Thanks to this well-made adapter, I can use all Pentax lenses on my Sony A3000, even the most modern ones. The presence of the membrane ring is a significant plus

excellent product at an honest price, the functionality of the aperture is maintained even on the Pentax DA lenses that do not have an aperture, although it is actually not clear which F it is shooting at. Flawless construction both on the machine and optical side, one of the best adapter rings I've tried.

Perfect for using my Pentax lenses on my Sony a5100. Also works in video mode. I recommend
