Designed for 4K, 6K, and 8K productions, this 7-stop, 4 x 5.65" Schneider RHOdium Full Spectrum ND Filter features a 128x filter factor that provides a 7-stop exposure reduction. It helps you control IR contamination within the full visible and into the near infra-red spectrum. The neutral density material is sandwiched between two layers of white water glass, which prevents subtle color shifts that can occur with regular ND filters.

With the ND material sandwiched between glass it is protected from being affected by cleaning and polishing of the outside filter glass, which makes it an excellent choice whether you are a rental house or owner/operator. RHOdium Full Spectrum ND filters are the first to be tested using a tristimulus scan, which is a more critical color measurement method than previously used.

A: No, there is not currently a NiSi branded case for the NiSi Full Spectrum FS ND Drop-In Filter for ATHENA Lenses (7-Stop).

Q: 5. How does it compare to B+W Vario ND 1-5? What is the front size? B+W's front size is designed at 86mm for less vignette. Even so, I did find vigenette at 24mm on my 24-105 lens. How about the color shifting? B+W is shifting green on 1-3 stops.

A: The front filter thread of this filter is 82mm. Most filters will begin to vignette to some degree at 24mm. Color shift is nearly always present when using variable ND filters, but how much varies between filters.
