The ARRI ALEXA LF 0.3 FSND Filter is a large-format, neutral density filter providing a 1-stop reduction in exposure. A full-spectrum coating attenuates the light passing through the filter while maintaining a perfectly neutral color balance. This filter's behind-the-lens design reduces weight and reflections when compared to using a matte box-mounted filter while also adding protection for the camera sensor.
Compatibility
ALEXA LF camera.
Multicoated Optical Glass
- A broadband, antireflective multicoating both reduces reflections and ensures high image contrast.
- The water-white glass is precision polished, creating perfectly parallel surfaces, guaranteeing a clear, sharp image.
Shimming
- In-camera filtration will change your flange focal depth. Therefore, all internal filters require a properly shimmed lens mount.
- Use only the original LF IFM shim when filtering with the LF IFM.
- To compensate for the change in flange focal depth due to the shim, always insert the LF IFM optical clear filter when no ND filtering is needed.
Note:
When the camera is no longer shimmed for the LF IFM, the glassless LF IFM empty filter frame must be placed back into the filter position.
