The ARRI ALEXA LF FSND 2.4 is a high-performance Full Spectrum Neutral Density filter designed for the ALEXA Internal Filter Module. By positioning the filter behind the lens rather than in front, cinematographers can maintain superior image quality while streamlining their camera rig.
Superior Image Quality and Efficiency
FSND filters are engineered to maintain a perfectly neutral color balance across all densities, ensuring that skin tones and color palettes remain consistent. Filtering behind the lens offers several technical advantages:
Reduced Weight: Eliminates the need for heavy glass in the matte box.
Minimized Reflections: Significantly reduces internal reflections and narcissism compared to front-mounted filters.
Workflow Speed: Enables faster filter swaps without adjusting external accessories.
Compatibility and Installation
This filter is specifically compatible with the ALEXA LF internal filter module. Please note that FSND filters are not compatible with any generation of the ALEXA Studio. To ensure optical precision, the supplied shim must be used to adjust the camera's flange focal depth accordingly when the filter is installed.
