Menu Guide
This option controls how autofocus 
adjusts to changes in the distance to the 
subject when AF-C is selected during 
viewfinder photography.
❚❚ Blocked Shot AF Response
Choose how quickly focus responds when something passes 
between the subject and the camera. Choose from values 
between 5 (Delayed) and 1 (Quick). The higher the value, the 
slower the response and the less likely you are to lose focus on 
your original subject. The lower the value, the quicker the 
response and the easier it is to shift focus to objects crossing 
your field of view. Note that 2 and 1 (Quick) are equivalent to 3 
when 3D-tracking or auto-area AF is selected for AF-area mode.
❚❚ Subject Motion
Select Steady for smooth focus when photographing subjects 
that approach the camera at a steady pace, or Erratic for 
improved response when photographing subjects prone to 
sudden starts and stops.
