Ok, I tried this and it seemed to work (most of the time). I didn't like the bits of foil left behind, so is there another method to address this? I tried to search, but must not have the right index words...thanks.
Also interesting in that the Vivitar 50mm 2.0 Auto works in all modes on the K-01 but stays fully open on the K-3. Annoying.

Ok, all apologies if this was covered and I missed it. I've read this great thread on using manual lenses on my Pentax K-3, and had success with almost all of my manual lenses (Access P-MC 70-210mm 1:3.5, MC Cosmicar 70-200mm 1:4, MC Cosmicar 28-80mm 1:3.5-4.5 and Super Takumar 50mm 1:1.4 M42 mount); all work well. However, when I try my Vivitar 50mm 1:2.0 lens, I lose control of the aperature ring. It does have the black surface and from the sounds of it, I should just drill another stop in it. Sounds good.
But, this lens works just fine on my K-01 and on my K-200D using the instructions provided herein. Why wouldn't the K-3?!?
I bought a Spyder LensCal and have been taking pictures of it for lens adjustment as well as to establish the sharpness envelope of each lens (including my 43mm Ltd, 40mm XS, 18-55 WR zoom and Sigma 50-200). Interesting results...
Thanks
