INTERCHANGEABLE OLPFS
This section describes the interchangeable optical low pass filter (OLPF) system and modular OLPFs.
The camera system includes intelligent, modular OLPFs. The camera automatically recognizes the OLPF type installed,
eliminating the need to configure OLPF settings in the camera menu.
RED offers the following modular DSMC2 interchangeable OLPFs:

DSMC2 OLPF REVISIONS AND COMPATIBILITY
DSMC2 OPLFs shipped through October 2016 have curved glare stops at the top and bottom of the OLPF. DSMC2
OLPFs shipped after October 2016 have straight glare stops. The images below show the difference between the
original (curved glare stops) and modified (straight glare stops) DSMC2 OLPFs:
Figure: Original DSMC2 OLPF, Curved Glare Stops (Left); and Modified DSMC2 OLPF, Straight Glare Stops (Right)
The modified DSMC2 OLPFs (straight glare stops) are incompatible with the following lenses due to their protruding
rear elements:
Leica Super-Elmar-M 18mm f/3.8 ASPH
Leica Super-Elmar-M 21mm f/3.4 ASPH
Other lenses that have very long protruding rear elements and require the Leica M Mount may not be fully compatible
with the modified DSMC2 OLPFs (straight glare stops).
If your setup requires the lenses listed above, enure that you use the earlier revision of the DSMC2 OLPF (the revision
with the curved glare stops). If you do not have the earlier revision of the DSMC2 OLPF and need it, contact your
Bomb Squad representative.
