Preparatory step 3:
Forward-Backward Adjustment:
Now bring the camera to a precise vertical posi-

tion. For this purpose use the rotator stop screw
(6) and the 90° marking.
Mount the lens, whose entrance pupil position you

want to find, to the camera body. When using a
zoom lens, set the required focal length. In the
following, you need a one-time set-up for testing.
This set-up, should have vertical lines in the fore-
ground as well as in the background.

6. Now set another distance on the upper arm. Open the locking screw (3) a bit,
move the quick release at the upper arm a few mm forward or backward and
tighten up the screw. When panning again you will notice that the movement of
the lines will either be stronger or weaker. In the last case you shifted the quick
release in the right direction.

3. Look through the viewfinder. Find
a vertical edge or line, such as a
floor lamp, which is located in the
foreground and bring it in line with
a vertical object in the background
e.g. a door frame (fig. 1).
4. Now pan the camera from right
to left and back while looking
fig. 2
through the viewfinder. Observe
if the objects move to each other
(see fig. 1+2) or stay together (see
fig. 3+4).
5. Here: When panned the camera to
right, the floor lamp moved to left
in relation to the door frame (fig.
2). This is an indication of rotating
outside the entrance pupil.

Crosswise quick release installation on the upper arm
(Alternative to lengthwise installation)
Only when using a camera, whose tripod socket is in line
1
with the optical axis, the crosswise installation is useful (see
illustration below).
Big advantages are: You have fast and easy access to the
quick release locking screw (1) from above, the possibility
to extend the available adjustment range (e.g. with a longer
camera-plate) and it's not necessary to adjust the height
Crosswise instal-
(compared to lenghtway installation).
lation
optical axis
When installing the plate on the camera bottom, please note that the engraved
scale is aligned to the top, so that you can easily see it later from above.
Left illustration: The tripod socket is in line
with the optical axis. Usually the case with
bigger mirrorless- or DSLR-cameras.
When using such a camera, the already dis-
cussed lengthwise installation is possible
just like the crosswise quick release in-
stallation on the upper arm. In the last case
you have to mount the camera-plate parallel
to the optical axis, meaning perpendicular to
the cameras bottom edge.
By installing the camera-plate as far as pos-
sible forward or backward, you can extend
the available adjustment range. However,
this is only needed in very rare cases, e.g.
when using especially long zoom lenses
with very big cameras or very short lenses
on very small cam-
eras.
