3-1-3. File Data at Adjustment

The file structure of the adjustment data of F35 is as
follows.
Scene
Lens
Reference
OHB
. Lens file is used for compensation of the deviation
which is generated by switching the lens extender from
OFF to ON and for compensation of the difference in the
characteristics between lenses. This file is stored in the
camera. Mount the lens actually used during the adjust-
ment.
. The reference file stores the custom paint data adjusted
by the video engineer. This file is stored in the camera
and memory stick. Therefore, before performing adjust-
ment, store this data in the memory stick first, and reset
this data from the memory stick after adjustment.
. OHB file is used for adjustment of the CCD block
maintenance. This file is stored in the camera.
