The Ice 86mm 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.

This filter is constructed from optical glass for clarity as well as color fidelity and features an aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect. To prevent internal ghosting and reflections, each glass surface includes eight layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters.

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.

2x filter factor reduces exposure by 1 stop.

Multicoated to prevent internal ghosting and reflections.

Aluminum-alloy filter ring for durability while remaining lightweight.

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

86mm front filter threads allow for use with other filters.

Top knurling to provide a more textured grip when mounting or removing it from a lens.

Q: 1. Never heard of ICE. Does this produce a color cast?

A: ICE filters are made by Desmond Photographic. The Ice 82mm Slim Circular Polarizer Filter is neutral and should not have a color cast.

Q: 2. will this fit a Nikkor Af-S 50mm 1:1.4G lens?

A: Yes Nikon AF-S NIKKOR 50mm f/1.8G Lens is compatible with Nikon Circular Polarizer II Filter (58mm).

Q: 3. For this 52mm filter--is the front thread diameter also 52mm? Thanks!

A: The front thread is 52mm.

Q: 4. Will the Olympus hood for the Olympus 75mm f/1.8 Lens fit over this filter?

A: I am not familiar with this particular lens but as far as I know any 58mm lens cap will fit.I had no problem with my Canon 58mm lens cap.

Q: 5. Where are these manufactured ?

A: The ZEISS 82mm Carl ZEISS T* Circular Polarizer Filter is manufactured in Japan.

Q: 6. IS this polarizer brass or aluminum?

A: The ring is made of aluminum.

Q: 7. Does this come with the same case / cover system that the McKinnon Variable ND filter comes with?

A: It does not. The PM Variable ND Signature II comes with its round unique protector (hard cover + rubberized cover), and the Quartzline CPL comes with a square hard case with magnetic closure.

Q: 8. Can you use the lens hood on a Nikkor Z 24-70mm f2.8 S lens with this CP filter?

A: You can use them together but it will be difficult to adjust the polarizer.

Q: 9. What is the thickness of the filter?

A: The Ice Slim Multicoated Circular Polarizer Filter (100 x 100mm) is 0.08" / 2 mm, thick.

Q: 10. Will this 77mm filter fit onto the Canon RF 70-200mm f2.8 lens with the supplied Canon lens hood attached?

A: Yes, the Ice 77mm Slim Circular Polarizer will fit without obstruction from the RF 70-200mm f/2.8 lens hood. The lens hood has a filter window that you may open to spin the circular polarizer.
