Shimming the rods will raise the rods so that the M2 and other accessories such as a Follow Focus
and Matte Box will be properly aligned with the camera.
Shims come in 1/4”, 1/8”, and 1/16” thicknesses. Estimate the combination of shims required by
stacking them on top of the Hood up to the level of the top of the front lip of the Achromatic Lens.
Alternative methods for estimating the combination of shims are described below.
Alt-1
, Push the hood back for a clearer view of the
barrel inside the hood. Estimate shims needed
between barrel and inside of the Achromatic Lens.
Alt-2
, Remove the hood for an unobstructed view
of the barrel and Achromatic Lens.
Alt-3
, Place the Achromatic Lens in the hood, and
then estimate the shims required using the offset
between the back of the Achromatic Lens and the
Camera Lens.
(2) Remove the M2 Housing from the rods.
(3) Remove the rods from the Rod Support base plate.
Turn the base plate over and use the supplied
wrenches to remove the two screws that hold
the M2 Rod Support and Rod Clamp in place.
(4) Turn the base back over and set it on a flat surface. Lift the Rod Support part off of the base plate.
(5) Place the required shims on top of the base plate.
(6) Place the Rod Support part on top of the shims.
Turn the base, shims, and Rod Support
upright, using the flat surface to keep them
all aligned.
