1.8 SPC P
OSITIONING
PURPOSE
To align the SPC's center with the camera's optical axis. This can be done with
or without Multiple Tool II (or HS-I/F). If you do not use Multiple Tool II (or HS-
I/F), a bright penlight and expert skill will be required.
• Procedure Without Using Multiple Tool II or HS-I/F
This procedure requires expert skill. Until you become an expert at it, follow
CAUTION the procedure which uses the Multiple Tool II or HS-I/F to perform a final
check.
TOOLS
Bright penlight
EF 50mm f/1.8 lens
Instant glue
PREPARATIONS
1) Attach the EF 50mm f/1.8 lens to the camera.
2) While following the procedure for AF sensor positioning, use your hand to cover
the viewfinder and illuminate the SPC's side (clear portion) with the penlight.
3) Look through the lens and move the penlight so you can see the SPC's S0 and
other border lines. When doing this, cover the viewfinder so that the center
focusing point in the viewfinder is faintly visible. Also, keep the penlight at a
fixed position. This will make it easier to move the SPC.
ADJUSTMENT PROCEDURE
1) Move the SPC so that the SPC's S0 aligns with the viewfinder's center focusing
point.
2) Make fine adjustments so that it aligns with the center of the viewfinder's left
and right focusing points.
