Aperture Control
Works very well. The mount is secure on both the lens and the body side. I can't detect any play. Machined from aliminum the build quality seems very good. It is not explained in the product description but the biggest feature of this lens adapter compared to other K-NEX adapters is that it provides aperture control. This is important for Pentax K lenses that do not have an aperture ring, for example DA 50mm f1.8. The aperture control is provided through a click-stop shiny ring. It clicks with authority and has perfect damping. You have to count the click stops to determine the aperture value but using the live preview on A6000, I have no problem judging the DOF. Another great feature is the matte black paint inside. Most others use shiny black which causes internal reflections and loss of contrast. Overall, I am very pleased with this adapter.

問題なく利用できます
Sony α７ⅲでDA★55F1.4を利用するために購入しました電子接点が無い為F値は00となりますが、私の環境では問題無く利用できています。

中心がずれる
PK/DA-EのアダプターとNEX C3を組み合わせてみたところ、レンズの中心（レンズ上面の距離指標の赤い線)がズレてしまいます。2枚目の写真のように、Pentax DA21mm F3.2 AL Limitedレンズの純正専用フードは角型なので正面からみるとズレが非常に明らかで、そのままではフードが本来の役割を果たさなくなってしまいます。同じレンズをPentaxのデジイチに装着するとそのようにならないので、K&F製アダプターのバヨネットマウントの爪の位置がずれているのでしょう。絞りの調整リングなどの機能も質感も問題がないだけに、（個体差かもしれませんが）非常に残念です。
