Selecting a lens file
With this camera, values, such as the compensation values,
which are specific to the mounted lens can be registered in
a lens file. You can perform necessary adjustments upon
replacement of lenses by merely invoking the registered
file.
Select the file using the subdisplay.
For lens file selection on the subdisplay, see "3-2-7
Selection of a Lens File" (page 40).
For details on the lens files, see "5-1 File Configuration"
(page 104).

Adjusting the flange focal length

Adjustment of the flange focal length (distance between
the lens mount attachment plane and the imaging plane) is
necessary in the following situations:
• The first time a lens is attached
• When changing lenses
• If the focus is not sharp at both telephoto and wide angle
when zooming
The flange focal length for this camera can be adjusted by
rotating the adjustment screw on the front panel.
Use an Allen wrench (7/64" diagonal):
