The ARRI IFM-1 set is an upgrade for ALEXA, ALEXA Plus, ALEXA Plus 4:3 and ALEXA M that replaces the reflex prevention cone inside the lens cavity with a filter holder that allows the manual insertion of an FSND (Full Spectrum Neutral Density) filter. Placing a filter between lens and sensor reduces weight, reflections and complexity. Includes:

- Internal filter holder
- IFM shim
- IFM upgrade tool
- IFM upgrade instructions - IFM manual

K2.72137.0 - FSND Filter Set (Basic)

Note: This upgrade can be performed by any ALEXA customer. The basic filter set includes FSND 0.6, 1.2 and 1.8 filters and an optical clear. The remaining five FSND filters can be purchased in the completion filter set. Not compatible with ALEXA Studio.
