Slant adjustment of Rear lens goup / Adjustment of Resolving power
Rear lens group unit
#45×3
#43A ～D
#66B・#66C
● Inspect the resolving power by light projection. In case the resolving power is irregular partially
on periphery compared to the center of chart, make a slant adjustment.
・In case the resolution is irregular due to front focus, make an adjustment by putting the washer (#66B or #66C)
on the irregular part, in order to even out.
・In case the resolution is irregular due to rear foucs, replace the reference washer (#43C (t=0.03mm)) with the
washer (#43D (t=0.02mm)) and make an adjustment by putting the washer (#66B or #66C) to even out.
● In case the resolving power of the periphery is out of standard compared to the center of chart,
make the following adjustment.
・In case the resolution is irregular due to front focus, put the thicker washer (#43) for adjustment so that it is
within standard.
・In case the resolution is irregular due to rear focus, put the thinner washer (#43) for adjustment so that it is within
standard.
※ Refer to “List of Standard resolving power” for standards of resolvng power.
Caution：After this adjustment, in case of loosening or removing the screw (#45)
of the rear lens goup unit, it is necessary to inspect the resolving power again.

Inspcet Encoder Signal
Use the F70 body and the inspection software for lens encoder signal, to display the encoder signal on PC.
How to inspect
● Start the inspection software for lens encoder signal and select “1. READING OF LENS ENCODER
SIGNAL".
Then, follow the instructions on the display.
● Encoder signal
When the distance scale ring is set in position, the encoder signal should be as follows.
In case the value of encoder brush is different from the above list, the following causes should be considered.
● Wrong position of the attached brush
● Malfunction of the brush or FPC
● Dirty encoder pattern of FPC
● Wrong position of attached FPC
