⑥
Insert the three alignment screwdrivers (long, middle, short) in the loosened screw holes of the rear lens
chamber, and loosen the screws.
Note) Because the screws cannot be seen, when inserting the alignment screwdrivers, put them straight down in
the screw holes so that the screws can be easily found.
⑦
Rotate the knobs of the micrometer (X and Y axes), and shift the cross lines by the scales that were results
of the chart shooting of the rear lens group alignment.
(e.g. Refer to "Pic.1" for the case of <X dire1, Y directions:-1>)
Caution:
When the knobs of the micrometer (X and Y axes) are rotated and the cross lines are unable to move, do not
forcedly rotate them.

⑧
After completing the above shifting of the cross lines, tighten three screws of the rear lens-G chamber with
the alignment screwdriver.
Caution: The intersection point of the cross lines is misaligned when the holder is moved up. So adjust
considering this misalignment.
⑨
Remove the alignment screwdrivers (long, middle, short) from the rear lens-G holder.
If the alignment driver remains inserted in the rear lens-G holder and the holder-moving lever is moved up,
the root portion of the screwdriver (long) touches the equipment.
