Designed for 4K, 6K, and 8K productions, this 9-stop, 6.6 x 6.6" Schneider RHOdium Full Spectrum ND Filter features a 512x filter factor that provides a 9-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.

• Filter does not affect coloration of the image and is ideal for use with other filters.
• Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased IR passing relative to visible light.
• Constructed from Schott water-white glass for increased optical clarity.
• Padded pouch included for storage and transport.

Q: 1. Is there a case available for these yet? Looking to clip somewhere between 3 and 7 of them to my belt for gimbal work.

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). However, you could consider using a case like the ARRI Camera Assistant Belt Pouch (Large), BH #ARK20013016, or the WANDRD D1 Fanny Pack (Wasatch Green), BH #WAD1FPWG2, to carry several of the filters.

Q: 2. zv-e1 can use this?

A: No, the manufacturer of the Kolari Vision Magnetic Clip-In ND Filter for Sony E-Mount Full Frame Cameras (6-Stop) does not list the Sony ZV-E1 Mirrorless Camera (B&H # SOZVE1B) in their compatibility.

Q: 3. 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.

Q: 4. Does this fit A7C?

A: Yes it can fit the Kolari Vision Magnetic Clip-In ND Filter for Sony E-Mount Full Frame Cameras (3-Stop) but you need the Magnetic Mounting Plate for it to work in the a7c and the a1. That part at this time is only available direct from Kolari Vision.

Q: 6. The overview for this Variable ND filter states that the effect is achieved by "...stacking highly neutral gray polarizing filters..." If so, will this filter also work as a good polarizing filter? I need a polarizer + ND filter for waterfall photography, so I was wondering whether a separate polarizing filter is needed in combination with this filter.

A: The Schneider True-Match Vari-ND MKII Variable Neutral Density Filter (82mm) does not act as a Polarizing Filter. A separate Polarizing Filter is necessary to get the Polarizing effect.
