TOUCH TRACK 
Dynamically updating positionable AF using touchscreen. Works with Spot Zone only. Keep AF Spot on 
subject while moving across frame, will continuously focus on spot. 
RACK 
For quickly selecting two focus points and executing rack focus between them. Focus points are selected 
using the Touchscreen. Shutter half-press executes rack movement. Works with Spot Zone only. 
Rack mode remembers the last Center or Spot position and focus setting as the first rack point. A second 
rack point needs to be defined by moving the spot window to the desired second location. If the spot 
window is not moved, a shutter half-press will only cause the lens to execute a single AF adjustment on the 
original Spot. On the other hand, when two rack points have already been defined, the rack point can be 
updated by moving the spot to a new location. This will replace the rack point that is not in focus at that 
moment. 
ZONES 
Available options are CENTER and SPOT. Default is CENTER. This control allows selection of the boxes 
used to indicate objects in/out of focus.
