"Crippled" KAF mount - explain this to me
The mount is crippled because it can not read where the aperture is set on M lenses. If you hit the AEL button, the lens will meter at that moment. It is rather easy. I have no issues with it. In fact, the lens I use the most on my K2000 is a manual Zenitar 16.
BTW - the best JPEG setting I found so far is
+1 Fine Sharpness
Variance is Evil!
