I picked up a Tamron Adaptall 2 28mm lens in really good condition and I have a couple of PKA Adaptall mounts so it was ready to work. I took it straight to the local Volkswagen show to give it a test. The shots seem overexposed by about one stop, but that is easy to fix in MS photo editor, samples here have been adjusted to fix that. I will experiment further, but that is a reasonably common issue with the Adaptall PKA mounts anyway, so I will try another mount.
Now I have an auto aperture 28mm lens for when I need one, but when I have time on my side I will use the Pentax-M 28mm/f3.5.
