Old lenses on new bodies

    I know this has been covered umpteen times, but there's one thing that's puzzling me.

    My Pentax 50mm M lens works in the Manual or Av (wide open only) modes on my GX-1S. The same lens is fully operational in Av mode on my ME Super. Why is this?

    Ah, I've figured it out: that's why the KAF2 mount is called 'crippled'.

    See other threads on this matter. The K & M series will work at any aperture if you 'enable aperture ring' in the custom menu - but only in stoppped down mode. I use old lenses all the time on my K10 with no problems whatsoever.
