Replacing the Lens Mount (Optional/Additional)
Redrock Micro provides a number of lens mounts that can be purchased separately and will enable
you to use a variety of lenses, including professional film camera lenses, with your M2 Cinema Lens
Adapter.
The lens mount assembly on the M2 Housing consists of the
lens mount
, which is the part that
connects to the 35mm lens, and the
flange
, which is the metal tube that connects to the M2 Housing
and provides a seat for the lens mount.
The flange provides a solid support for the lens mount and provides the proper distance between the
back of the 35mm lens and the Cinescreen, called the Flange Focal Length (FFL).
Some lens mounts share the same flange. In this case, only the lens mount itself must be replaced.
The Nikon, Canon FD, Olympus, and Minolta lens mounts share the same flange.
Some lens mounts require a different FFL or unique lens mounting mechanism, and require replacing
the lens mount and the flange. The lens mounts requiring specialized individual flanges are the PL,
OCT-19, Canon EOS, Pentax, and other still camera lens mounts.
Replacing the Lens Mount
(1) There are three set screws on the flange. Loosen them but
DO NOT REMOVE
them. The mount
pops out.
(2) Insert the new mount.
(3) Orient the mount. The positioning of the lens alignment dot on the mount is important. The lens
alignment dot on the 35mm lens will line up with the corresponding dot on the mount. Position the dot
so that the lens markings, such as the aperture setting, will be clearly visible (typically on top) when
the lens is mounted.
(4) Re-tighten the screws.
