The ARRI ALEXA LF FSND 0.9 is a precision-engineered internal filter designed for the ALEXA LF camera system. By positioning the filter behind the lens rather than in front, cinematographers can significantly reduce setup complexity, minimize external reflections, and lower the overall weight of the camera rig.
ARRI Full Spectrum Neutral Density (FSND) filters are renowned for maintaining a perfectly neutral color balance across all densities, ensuring consistent image quality without color shifts. This internal module also effectively reduces narcissism (internal sensor reflections) that can occur with traditional front-mounted filters.
Compatibility and Technical Requirements
Camera Support: Specifically designed for the ALEXA LF internal filter module.
Studio Compatibility: These filters are not compatible with any generation of ALEXA Studio cameras.
Flange Focal Depth: To maintain optical precision, the included shim must be installed to adjust the camera's flange focal depth when using FSND filters.
