URPOSE
:
To align the center of the SPC sensor with the center of the camera’s optical axis. To do
the adjustment, you can either use Multiple Tool II and HS-I/F or
not use them at all. If you do not use these tools, you will need a bright
penlight and expert skill.

P
REPARATIONS
:
1) Attach an EF 50mm f/1.8 lens to the camera.
2) While covering part of the viewfinder with your hand, use a penlight to illuminate
the SPC side (clear portion) within the AF sensor positioning area.
3) Look through the lens and move the penlight so that you can see the SPC's S14 and
adjacent boundary lines. To make it easier, cover part of the viewfinder so that the
focusing point at the viewfinder's center looks faint. Also, fixing the penlight in place
makes it easier to move the SPC.
A
DJUSTMENT
:
1) Move the SPC so that S14 is aligned with the focusing point at the viewfinder's
center.
2) Make fine adjustments so that the focusing points on the left and right of the
viewfinder are also centered.
