Jens I have never had a problem with "back focus" with my istD, however in low light situations with my D1 it does happen. Camera tends to focus on an object further that what you really want. The finder in the D1 is very good, and i can usually tell if i'm off,then i just refocus.
The only time i really see this is during the two indoor horse shows i do, as the lighting is very poor.
