Ever had a lens/body combination which just won't work?

haha

Need to take both lenses out for some exercise now.

But dang, that was a good deal on the 2nd lens.

DA50 1.8 and FA50 1.4 will not work on my K-50; AF adjustment would need to be about -11 for it to focus correctly wide open. at -10 it is just ever so slightly off, and wide open the DoF is small enough at portrait distances to show it. Funny thing is I tried the FA on a K1 and it also required and adjustment... of -2, and I tried the DA on a K3-II and it required a -1. Neither of the other two cameras I tested need any other lens I have to be above +10, which means for whatever reason my K-50 hates 50mm at wide apertures. Anything at f/5.6 or narrower images are tack sharp.
