I had the same problem with my *istD and the K100D with a FA24-90 lens that back focused also. Drove me crazy. My FA85f1.4 also has focus issues, but only when I manually focus. I never had a problem with film cameras in this regard, I wonder what makes digital cameras different that this comes up pretty often in the Pentax discussion groups.
