Performance of Auto Focus may be reduced under the following conditions:
The subject is dark or distant.
There is inadequate contrast between the subject and background.
The scene has reflective highlights.
The subject is backlit.
There is inadequate surface contrast/detail inside the window.
NOTE:
Edge Mode can be used for additional assistance in these conditions. Refer to EDGE.
M ANUA L
When selected, all focus operations are manual.
CO NFI RM
Enables the Center or Spot focus target square. This mode provides additional focus assistance to the
photographer using RED, YELLOW, and GREEN color changes to the focus spot window. Inadequate subject
illumination and/or contrast may interfere with normal Focus Confirm operation.
For best results with Focus Confirm, operators should 'rock' the focus ring -- focusing through the point of
optimum focusing and back again in decreasing amplitude -- as when 'zeroing-in' for precision manual
focus.
S I NG LE
A Focus / Record Button half-press performs single-shot AF. Optimized for rapid focus even under low-
contrast conditions. Works with both Center and Spot Zones.
CO NTI NUO US
Once engaged with half-press, will attempt to keep objects in AF window in focus. Works best with good
lighting and contrast. Works with both Center and Spot Zones.
TO UCH TRA CK
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.
RA CK
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.
