The NiSi 95mm Pro Circular Polarizer Filterhelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

The NiSi 95mm Pro Circular Polarizer Filter is constructed from optical glass for clarity as well as color fidelity. It features a brass filter ring that can be rotated in order to adjust the intensity of the polarization effect while enhancing durability and jamming prevention. Additionally, one layer of NiSi Optical Nano Coating is applied to each of this filter's surfaces to create an improved beading effect when in contact with water for greater cleaning efficiency.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Polarizing filters arrange, and filter, directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light.

Clears up haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° angle from the sun.

Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.

NiSi Optical Nano Coating creates an improved beading effect when in contact with moisture for greater cleaning efficiency.

2 to 2.5x filter factor reduces exposure by 1 to 1.3 stops.

Constructed from optical glass for clarity.

Brass filter ring helps to prevent jamming, and provides additional strength.

Filter ring can be rotated to adjust the intensity of the polarization effect.

Side knurling to provide a more textured grip when mounting or removing filter from a lens.

95mm front filter threads allow for use with other filters.

Related Questions and Answers

Q: 1. Could someone please verify the Nisi-supplied exterior dimensions of 7"x5"x2"? That sounds awfully large for 95mm filters.

A: We measured the NiSi 8-caddy pouch at approximately 5-3/8" by 5-1/4" by 2-3/8".

Q: 2. Where is this product made?

A: Country of origin is China.

Q: 3. I thought this filter was coated. Why is it not? Thank you.

A: The non-coated filter is designated as "PRO C-PL". The coated (enhanced) CPL is designated as "Landscape NC-PL".

Q: 4. Are the metal rings made of brass or aluminium? Product overview sections mentioned as brass and aluminium in specifications.

A: The NiSi Pro Circular Polarizer Filter has brass filter rings. Not aluminum.

Q: 5. Does this filter screw onto the front element? Or is it made to use with filter holder system only? I need it for my Canon 24-70L II, which has an 82mm thread. Thank you.

A: Yes, it is a regular screw in type filter.

Q: 6. Is this a dual ring filter where you can turn the filter and make sure the lines of polarization are horizontal?

A: Yes. The NiSi 95mm Pro Circular Polarizer Filter has 2 rings. One rotates to change the polarization in the scene.

Q: 7. Any difference between BH #NINIPV7CPLNC (NIP-V7-CPL-NC) & BH #NIPV5CPLNC (NIP-V5-CPL-NC) filters? Both work w/ NisiV5Pro holder?

A: The optical qualities are the same between the NiSi 86mm Enhanced Circular Polarizer Filter for Select NiSi Filter Holder Kits (MFR #NIP-V5-CPL-NC) and the NiSi Enhanced Landscape CPL Filter for NiSi 100mm V7 Holder (MFR #NIP-V7-CPL-NC). The V7-CPL for the V7 holder would only work with that holder. The V5-CPL would work with the V5 and V6 holders.

Q: 8. can I use for 82mm filters?

A: This caddy works for any filter that is 95mm and below.

Q: 9. Can I fit 2 Canon Drop-In Filters for the EOS-R filter adapter?

A: Yes, this pouch can hold the drop in filters for the Canon Drop-In Filter Mount Adapter EF-EOS R.

Q: 10. Is this filter (BH #NINIPV7CPLNC MFR #NIP-V7-CPL-NC) compatible with Nisi V5Pro filter holder?

A: Yes, the NiSi Enhanced Landscape CPL Filter for NiSi 100mm V7 Holder is compatible with the Nisi V5 Pro system.
