If necessary, use a clamp to secure the lens cable in

Adjusting the Flange Focal Length
Adjustment of the flange focal length (the 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 can be more precisely adjusted by
using the focus assist indicators.
For details about focus assist indicators, see "Displaying the
focus assist indicators" (page 15).
Note
The various parts of the lens used in adjusting the flange focal
length are in different positions on different lenses. Refer to
the operation manual for the particular lens.
