pin on the seat of the viewfinder and align the pin with the hole in
the flange of the finder. Make the flange to the seat of the viewfin-
der and tighten the lock ring until it is set firmly in place. During
this procedure, you will notice that the extension finder needs to
face 180° away from the operator’s eye to be installed on the view-
finder. Because of its optical construction, this is completely normal.
After installation, rotate the finder 180° to regular viewing position.
2.2.3 Viewfinder Tension Adjustments
The large knurled knob at the base of the left/right lateral move-
ment point (B) locks the lateral positioning.
The friction adjusting ring, located behind the eyepiece lock ring,
can be used to adjust the tension of the eyepiece swivel, depending
on the operator’s preference and the viewfinder being used.
When using the standard eyepiece, tension should be relatively light
to allow for movement with a moderate amount of pressure.
When using a standard extension finder, tension should be increased
to hold the additional weight of this finder in place.
To adjust the tension of the swivel, loosen the steel knurled screw
(C) located on the friction adjusting ring. Hold the eyepiece in pla-
ce, rotate the adjusting ring slightly and retighten the screw; 1/8 of a
turn, at first, will have an effect. To increase the tension of the eye-
piece swivel, rotate the adjusting ring clockwise; to decrease the ten-
sion, rotate the adjusting ring counter-clockwise.
2.2.4 Adjusting the Diopter
Before shooting, the diopter setting of the viewfinder should be
adjusted to the operator’s eye. To set the diopter, locate the diopter
set ring (D) in front of the carrying handle at the top of the viewfin-
der, and loosen the small knurled knob. Look through the viewfin-
der, rotate the diopter set ring until the edge of the cross-hair is at
its sharpest point and retighten the knob. It is recommended that,
for easiest setting, this adjustment be performed with the port cover
off and no lens on the camera.
Notice that the diopter set ring is engraved with numbers and dots
