8.1 ND filter module
NOTICE
ALEXA Mini uses FSND (Full Spectrum Neutral Density) filters, which are linear
across the full spectrum of the camera sensor. This prevents artifacts from infrared
wavelengths and the need for additional IR filters.
The camera contains an internal ND filter module, consisting of ND 0 (Clear), 0.6, 1.2
and 2.1 filters. The filters can be operated via user buttons or the MVF-1.
