ADJUSTING THE BACK-FOCUS
Optimo Ultra Compact is set with the 52mm industry PL flange distance and delivered with a color shim set. If you need to adjust the
back focus flange to fit more accurately to the position of the sensor on the camera, you need to modify the rear color shim thickness.
Please proceed as follow; any possible combination of shims can be used to achieve the required thickness and therefore the required
flange focal distance. Please keep the rear filter (1) in place and be sure it is well fitted when doing the back-focus adjustment
.
- Unscrew the PL retainer (5) anticlockwise
- Remove the PL sub-assembly (1, 2, 3, 4, and 5)
- Unscrew the screws (6) then remove the aluminum installed shims (7) and the installed colors
shimmed (8) by using a flat-bladed screw-driver or a pair of tweezers.
- Determine the total thickness of the shims already installed. Increase or decrease the total
shim thickness according your needs
- Put back all elements in reverse order
CAUTION: do always put back the aluminum factory shim (7) on the color shims. Be sure the
color shims and the aluminum shims are in place with the indexation pin (9)
