The camera system includes intelligent, interchangeable optical low pass filters (OLPFs). The camera automatically recognizes the OLPF type installed, eliminating the need to configure OLPF settings in the camera menu.

DSMC2 S35 OLPF Revisions and Compatibility

DSMC2 S35 OPLFs shipped through October 2016 have curved glare stops at the top and bottom of the OLPF. DSMC2 S35 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 S35 OLPFs:

Figure: Original DSMC2 S35 OLPF, Curved Glare Stops (Left); and Modified DSMC2 S35 OLPF, Straight Glare Stops (Right)

The modified DSMC2 S35 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 S35 OLPFs (straight glare stops).

If your setup requires the lenses listed above, use the earlier revision of the DSMC2 S35 OLPF (the revision with the curved glare stops). If you do not have the earlier revision of the DSMC2 S35 OLPF and need it, submit a Support ticket at https://support.red.com.
