"BACK-FOCUS SETUP" screen
The back focus setting type is selected and fine adjustment is performed. The following setting
is performed on the "BACK-FOCUS SETUP" screen through the top screen. Refer to pages 24 -
25 for how to call up the screen. The lens adjustment (
☞
pages 15 - 17) shall be performed
before the back focus adjustment.
<Back focus adjustment>
The back focus adjustment is performed by changing the distance between the lens and focal
point.
Important:
• The auto back focus function is used for back focus adjustment at installation and for focus
correction at switching between the color and black-and-white modes after installation. This
function is not a function that is supposed to be operated continuously such as the auto
focus function.
• When focus missing occurs due to secular change in the lens and installation environment
or peripheral temperature change, the back focus adjustment is required again.
Note:
• The back focus adjustment can be also performed through the operation buttons. (
