Diamond cut from crystal-clear, water-white optical glass, Schneider filters are ground and polished to a precise flatness and planeparallelism (exact parallel relationship between front and back filter surfaces). Then, to ensure perfection, this is verified by a laser interferometer. Schneider filters are then checked with a densitometer for consistent density, and tested with a spectrophotometer for proper light transmission. It's due to this ultra-high consistency, that allows cinematographers to swap like filters mid-shoot with no discernible variation in color or effect. What's more, the unprecedented purity, color saturation and repeatability of Schneider filters virtually eliminate the need for lab color timing correction.

• Consistent precision
• Ultra durability
• Schneider filters work with long lenses

Schneider filters stand up to the most rigorous demands on set or location. They feature Schneider's specially formulated hard anti-reflective (AR) coating to resist flaking, peeling and scratching. This proprietary coating also reduces light loss and flare to less than 1% per surface, compared to untreated glass that has a light loss of 4% per surface. Schneider screw-in filters feature virtually jam-proof brass precision mounting rings, while unmounted Schneider laminated filters are protected against delamination and edge-chipping by Schneider's unique Edge Seal, which also reduces edge reflection and edge flare.

The common perception among photographers and cinematographer's is that filters should not be used in front of long length lenses, due to the critically short depth of field of these lenses. This belief is often confirmed when poorly made glass or "plasticresin" filters are placed in front of a long lens, and the degradation of the image is visible simply by looking through the viewfinder. This degradation is caused by poor quality control, low-quality glass and poor glass grinding and polishing techniques used in the manufacture of such filters. Schneider filters have no such problems, and can be used in front of even the longest lens. Diamond-cut from high-quality optical glass, then ground and polished to precise lens-making standards, Schneider filters offer unsurpassed clarity, light transmission and color saturation with absolutely no visible compromise of image quality. Even when stacked, they are the clear choice for use with any lens.

Q: 1. How do I rotate the Nikon C-PL 460 Slip-In Circular Polarizer? to adjust to get rid of glare?

A: The Nikon C-PL460 Slip-In Circular Polarizer has a dial/gear on the top that rotates the filter.

Q: 2. Is it threaded to hold a 40.5mm ND filter like the standard tray in the 400 2.8?

A: No, the Sony Drop-In Circular Polarizing Filter for Sony FE 400mm f/2.8 GM OSS Lens is strictly for polarization and cannot have the filter changed.

Q: 3. What filter needed for Nikkor ED SWM AF-S 400mm f2.8?

A: Nikon 400mm lens come with a drop-in filter. If you want a polarizing filter, the 40.5mm drop-in filter only works in the Nikon AFS 400mm f2.8E FL ED VR. This is the current model. The older AFS 400mm f2.9 requires the 52mm Circular Polarizer (C-PL1L).

Q: 4. Does the circular polarizer for the FE400 also fit the FE600?

A: Yes, this filter and its holder will work in the FE 600mm and all Sony telephotos with drop-in filters.

Q: 5. Do you have 5 stop and a 10 stop ND filters that will screw in to these drop in filter holders?

A: The Nikon AF-S NIKKOR 400mm f/2.8E FL ED VR lens came with a drop in filter holder and a clear filter. You can remove the clear filter from your original holder and use any 40,5mm filter in the holder instead such as this 5 stop ND: https://bhpho.to/4al5eNO

Q: 6. I have both a 200mm and 800mm Nikon lense that use the same drop-in 52mm Circular Polarizer Glass Filter. For $200 the filter should come with a practical case in which to store the clear glass filter, which must be temporally removed from the lens. The large plastic case the C-PL3L Polarizer comes in is nothing but a fragile shipping case. What can you recommend as a compact durable protective case?

A: This is the type I used for years on movie sets. B+W E1 Filter Pouch - Holds 1 B+W Filter up to 77mm B&H # BWFP77 . Here is one that is very soft. OP/TECH USA Soft Photo/Electronics Wide Body Pouch, Small (Black) B&H # OPPPWBSB. This one will hold three filters. Sensei Three Pocket Filter Pouch (Up to 77mm) B&H # SEFP3P77B. None of these I like that much because they do not completely seal. So I also suggest these Porta Brace bags. They may be too big but they zipper close unlike the others that allow dust in. Porta Brace Filter Pouch Set for up to 3 Circular Filters up to 4.5" B&H # POFILTERPOCH

Q: 7. Is the filter adjustment ring water resistant? Seems like a place that could potentially let in water into the lens during rain.

A: I am not sure but its a direct replacement for the filter that comes with the lens. I use a Thinktank cover any time Im shooting where the lens could get wet.

Q: 8. Does this work with the Bright Tangerine Misfit Kick Matte Box?

A: Yes. The Lindsey Optics 138mm Brilliant Rota-Pol Circular Polarizer for 4 x 5.65" Cine Matte Boxes will work in the Bright Tangerine Misfit Kick Matte Box.

Q: 9. Will the Nikon 2221 slip in filter work with the 400mm S lens?

A: No, the Nikon 40.5mm Drop-in Circular Polarizing Filter MFR 2221 ( https://bhpho.to/3J8jCvk ) is not compatible with the NIKKOR Z 400mm f/2.8 TC VR S lens. The Nikon C-PL460 Slip-In Circular Polarizer is compatible with the 400m S lens.

Q: 10. Can the actual circular filter be removed and replaced with another filter ?

A: No, the filter in the Sony Drop-In Circular Polarizing Filter for Sony FE 400mm f/2.8 GM OSS Lens cannot be removed and replaced.
