You haven't said that you did a decentreing test when you first purchased?
No, I didn't. That would have probably been about 10 years and 3 SDM motors ago...
Why would it FF considerably during LV? Why is the FF/BF in OVF inconsistent? Why when focusing on objects closer to the lens, it produces a lovely sharp image, but objects further away are a guessing game as to whether they'll be in focus? It's a beautiful lens, but Pentax AF in general continues to leave lots to be desired.
