This NiSi 86mm Circular Polarizer Filter for NiSi Holder Kitsis designed for use with NiSi 100mm or C4-series filter holder kits. It 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.

This enhanced circular polarizer filter is designed to provide a saturation effect that is approximately 25% greater than a NiSi 86mm Circular Polarizer for select NiSi filter holder kits. It is constructed from optical glass for clarity and features an aluminum-alloy filter ring for durability while remaining lightweight.

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

Q: 6. 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: 7. Do I need #NIPV7AD82 to use this CPL filter with the NiSI V7 Alpha 100mm Aluminum Filter Holder?

A: That is correct to use the NiSi Enhanced Landscape CPL Filter for NiSi 100mm V7 Holder on the NiSI V7 Alpha 100mm Aluminum Filter Holder you need the NiSi 82mm Main Adapter for 100mm V7 Filter Holder Kit, https://bhpho.to/3MPSJ1l .

Q: 8. I'm Looking to purchase the 86mm Landscape CPL but looking at the pictures here it does not have bluish tint like I'm seeing in all the reviews. Could you please confirm if this CPL is for sure the 86mm Landscape CPL and has the bluish tint?Thank you very much.

A: This is the NiSi 86mm Enhanced Circular Polarizer Filter for Select NiSi Filter Holder Kits B&H # NIPV5CPLNC MFR # NIP-V5-CPL-NC. The photo is off color.

Q: 9. Can this be used with the Nisi V6 holder system?

A: No, this is a standard screw in filter for a lens with a 95mm filter thread.

Q: 10. 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.
