Changing the position of the lens fixing lever
Remove the four screws from the face of the lens fixing
lever indicated in the figure. Change the position of the
fixing lever, reinsert the screws and securely tighten.
Adjusting the flange focal length
The optical section uses materials not susceptible to
thermal expansion, so flange back adjustment is generally
not required. However, if you want to make an adjustment,
remove the lens mount and replace the shim with one of the
appropriate thickness. At shipment, a 0.05 mm
(0.0020 inch) shim is installed. The following replacement
shims are available.
When using the camera in HFR mode, the lens distance
indicator may be slightly off, but this is not a malfunction.
For information about replacing shims, consult your local
Sony representative.
To change a shim
Exercise care not to damage the internal wiring of the
camera when changing the shim. Modifying a shim,
scratching a surface, or introducing dust can change the
flange back distance and damage the camera such that it
cannot be restored to original condition, just as for a film
camera.
1
Remove the lens mount screws (6).
2
Pull the lens mount out by about 10 mm (
13
/
32
inch)
and remove the shim carefully.
Pass the shim slit over the wiring, taking care not to
pull the wiring, when removing the shim.
Pulling the lens mount out by more than 20 mm
(
3
/
4
inch) risks damage to the internal wiring.
