Hey Max, I thought that I was the only one on the K100D + DA* lenses boat! However, I jumped ship and bought a K200D...
Anyways, I used the K100D non-SDM body for quite some time with the DA* 50-135... I'd say about 6 months, actually. It worked fine for me, and became one of my main 'gig/event' lenses... and just recently, my #1 wedding lens.
I also have the DA*16-50. On the K100D, it consistently mis-focuses, back focuses, front focuses, soft focuses... just not SHARP focus. It was frustrating cuz the picture turned out great but the focus would be off or something. On the K200D, the DA*16-50 now smartens up. I think the SAFVOX AF on the K200D is more well tuned for the DA*16-50 as the DA* lens now takes sharp pictures and only messes up due to user/photographer's error!
So if you have the K100D and plan to use it for a while longer, buy the DA*50-135 (But test it first) and upgrade your body before going for a DA* 16-50.
