The ALEXA LF FSND Filter Set (Full) provides a complete set of large-format, behind-the-lens neutral density filters, organized neatly in a carrying case. This set includes an LF IFM optical clear filter, and LF 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1 and 2.4 FSND Filters. Also included are an IFM (internal filter module) shim, a DG-1 IFM/extenders depth gauge, and a filter insertion tool. The IFM/Extenders Depth Gauge is used to check the compatibility of a lens with the camera when using the internal filter module, and/or an ARRI LDS lens extender. The IFM Shim must be added to any existing shims between the lens mount and camera when using any of the FSND filters, or the clear filter. The clear filter is used to avoid having to re-calibrate the depth after setting up the camera for internal FSND use.
