Thank you for purchasing a Cambo product.
The Actus-MV is a view camera system featuring lateral and vertical
shift, tilt and focus movement on the front and rear standard as well
as swing movement on the front standard. The Actus-MV is
compatible with a wide range of mirrorless and mirror reflex system
cameras.
The geared drives on rise/fall, shift and focus movements enable great
control over perspective, image displacement and high quality
panoramic stitching. Geared tilt and front swing movement enable the
photographer to optimize spatial sharpness. The rear focus and front
tilt movements are fitted with dual speed gearing for maximal
movement control.

1 Warnings
Due to the modularity of the Actus camera system, many
camera-lens combinations are possible. Please beware of the
possible collision of the rear lens element and the rear
standard and/or the sensor. Please note that Cambo is not
responsible for any damage done to the Actus, lens or
camera, due to improper or careless use.
Before changing the camera orientation form landscape to
portrait or vice-versa, ensure that there is enough clearance
between the camera body and the rear housing of the Actus.
If necessary (this depends on the camera body used) use the
vertical shift to lift the camera to gain more clearance.
Ensure that there is enough clearance between the camera
body and the rear housing of the Actus, before dismounting
the camera body.
(Over)exposure to direct sunlight or heat sources will damage
the leather bellows. Keep/store the leather bellows in a cool,
dry, dust-free and ventilated place.
The Actus uses disc magnets to mount the bellows. These
permanent magnets (magnetism N45) could cause temporary
or permanent damage to equipment
1
sensitive to magnetism
like magnetic cards (credit card, ATM card).
Beware that some combinations of swing, tilt, shift and focus
adjustments can dismount the bellows.
1
Please note that memory cards are not magnetic data carriers and will
therefore not be damaged by static magnetic fields.

1. Completely open the locking lever to the right
2. Slide the interface plate in the designated slot
3. Firmly push the locking lever left to fixate the interface plate

same interface and can also be fitted to the Actus-MV. Note these do
cause a limitation to the rise/fall range

in such way the dismounting pin [3] becomes visible through
the telescopic rail.
3. Use a narrow tool, for example a pencil, to press the spring
loaded pin and pull the front or rear standard towards the end
of the rail.
4. To re mount the front and rear standard, make sure to align
the angled area with the spring loaded pin.
