The NiSi 95mm Pro Circular Polarizer Filter helps 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.

Related Questions and Answers

Q: 1. Can this be used with a Tamron 15-30mm f/2.8 filter holder system?

A: This will not mount to the NiSi Tamron 15-30mm holder or any other holder for that lens that we are aware of.

Q: 2. Would I get vignetting at 14mm? I'd be using on the Nikkor S 14-30mm.

A: Tested it out, and none that we can see.

Q: 3. Are the pockets big enough to hold a 82mm Peter McKinnon PolarPro Variable ND filter (with the cap on)? They are about 18mm (3/4") thick x 96mm (3 3/34") around and I have two that I'd like a case for, along with a typical polarizing filter.

A: This case will definitely hold all those items individually. Though getting the filter in with the cap attached may be a bit of a squeeze.

Q: 4. 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: 5. can I use for 82mm filters?

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

Q: 6. 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: 7. 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: 8. Where is this product made?

A: Country of origin is China.

Q: 9. What are the dimensions and weight of the caddy?

A: 7"x2"x5" & 12oz

Q: 10. Can i stack a NISI ND Filter to this polarizer?

A: No problem!
