monitor while focusing.
Normal AF mode can be switched to Speed Priority AF mode by selecting

image will be dispayed when the shutter button is pressed halfway until
the AF is finished.

To return to normal AF mode, select [ Capture Settings] (P.27) →
[ Speed Priority AF] → [Off].
MANUAL FOCUS
In situations where autofocus or focus lock is not effective, you can focus
manually.

Turn the Focus ring until you get a clear
sharp image.
The green bar which appears on both sides of the meter
on the scale bar shows the depth of field. If you select
larger apertures, the depth of field will be shallower (area
in focus is narrower) and if you select smaller apertures,
the depth of field will be greater (area in focus is wider).

The focus point on the scale bar and the depth of field may differ from
the actual distance. Please use it as a guide only.
