     That's what I termed the AF-C "dead band" the distance you can move the camera before the camera refocuses, when I got the DA*16-50mm back from repair for a new SDM motor, I thought it still had a problem, such was the DOF fooling the system.

 

  Pentax's  dead band is huge compared to Nikon!
