17.1.2.1 FSND Filter Set (Basic) for ALEXA XT
17.1.2.2 IFM-1 Set for ALEXA Classic
ALEXA XT models come with an additional IFM-1 Empty Filter Frame.
This glassless filter ring serves as a placeholder for in-camera filters
and is not needed by ALEXA Classic cameras.
Therefore, preparing an ALEXA XT for internal filtration differs slightly
but crucially from preparing an ALEXA Classic (see Chapter Shimming
the lens mount on page 228).
The FSND Filter Set (Basic) for ALEXA XT models (except ALEXA XT
Studio) contains all components and filters essential for in-camera ND
filtering:
Storage Case
IFM Optical Clear (1) ND 0.0
Ground Glass/Frameglow tool (2)
IFM Shim (3)
Microfiber Cloth (4)
3 Internal Filters (5) FSND 0.6, 1.2, 1.8

The IFM-1 set for ALEXA Classic models (except ALEXA Studio) is
almost identical to that for ALEXA XT models. It additionally contains a
special IFM-1 wrench, and also some IFM-1 components that are pre-
installed in ALEXA XT models (marked by asterisk*):
