With technology taken from the ALEXA Mini and the AMIRA internal filters, ARRI Full Spectrum ND 1.5 Filter 6.6x6.6 5-Stopintroduces a line of external front full spectrum neutral density filters. The 6.6 x 6.6" ARRI Full Spectrum ND 1.5 Filter 6.6x6.6 5-Stopabsorbs 5 stops of light to reduce very bright illumination conditions, allow use of wide apertures, or add blur and motion effects to a subject during long exposures.

ARRI uses SCHOTT B270i glass for absolute flatness and pure neutral color rendition and hydrophobic and oleophobic coating for easy and fast cleaning. ARRI-coated filters provide lower reflectivity in the visible spectral range between 400 and 750nm and higher reflectivity in the near-infrared spectral range to produce a high dynamic range, improving color, neutrality, and contrast. Each filter has a unique engraved barcode for inventory and ID purposes and comes with a protective Cordura pouch lined with MICRODEAR antistatic cleaning cloth.

Related Questions and Answers

Q: 1. Why is it MORE expensive to buy just the filter without the adapter included?

A: While Canon sets the MSRP on their items, as of the time/date of this reply, the cost of the Canon Drop-In Variable ND Filter A (1.5-9 Stop), BH #CADIVNDFA, and the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND, on our website are currently the same price. However, I would simply recommend that if you are certain that you want the Variable ND Filter, as it is the most expensive of the filter options that are compatible for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, I would simply recommend to purchase the adapter kit that comes with the Variable ND filter, the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND.

Q: 2. Up to how many stops can it provide?

A: The headline and specs both say 1.5 to 9 stops.

Q: 3. Would this filter cause a colour shift when combined with the Hoya UV and IR Cut filter?

A: The Hoya 72mm Variable Density II Filter is meant to be color neutral without any color shift. This should not cause a color shift even if used with the Hoya 72mm UV and IR Cut Filter. One thing to keep watch for is an X-pattern near the maximum density.

Q: 4. does it let you know what stop its set at ?

A: It has reference marks.

Q: 5. How are these piece of glass shipped? I want to know how secured are they when it comes to shipping as I have never seen anyone do an unboxing video on filters like these. I'm afraid it might get broken in transit among other things.

A: The filter is stored in a Schneider's Padded Filter Pouch.

Q: 6. What is a recommended storage case for the filter when not in the adapter?

A: A Domke 11x11" Color Coded Protective Wrap (Gray), B H # DOPW11G would be a suitable option to store this filter. https://bhpho.to/3t8GR0O

Q: 7. Is there a non-variable ND drop in filter for this mount? Like a set of multiple NDs? I can't stand the color shift and increased contrast variable NDs create. I'd much prefer to just carry around a few drop in's at varying ND levels

A: We're afraid not. At this time Canon does not offer any alternative ND Filters for this system.

Q: 8. Will this drop in the Canon 300mm 2.8 just like the Polarizer Filter will?

A: Canon Drop-In Variable ND Filter A (1.5-9 Stop) is compatible only with the Canon Drop-In Filter Mount Adapter for EF-EOS - R lenses. It will not fit on Canon EF 300mm f/2.8L IS II USM Lens. You can use fixed ND filters with the following product: 1-Canon - Drop-In Filter Holder for 52mm Screw-In Filters BH #CAFHS52 https://www.bhphotovideo.com/c/product/186092-REG/Canon_2612A002_Drop_In_Filter_Holder_for.html/accessories
