The Ice 77mm 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.

77mm 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.

Constructed from optical glass for clarity and color fidelity.

Plastic filter case for storage and transport.

Related Questions and Answers

Q: 1. Whether this filter can be used together with another VND Filter?

A: Yes, you can stack filters but be aware you may get vignetting when used with a wide angle lens.

Q: 2. Hi everyone, besides of the fact that this filter makes your pictures pop, does it also protect the lens as well? (The lens I have is the Zeiss Batis 25mm f/2 with Sony A6000) Thank you.

A: Yes it does protect. Excellent alternative if you don't mined the light reduction

Q: 3. will it fit a sony 200-600mm lens

A: Yes, the Sony 200-600mm has a 95mm front filter thread, so this filter will fit.

Q: 4. 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: 5. 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: 6. Does this product fit with a lens hood?

A: A 77mm screw in lens hood or addtional filter will attach without problem. depending on lens though, attention needs to be paid to any potential vignetting that may occur with wide angle lenses. Also, some bayonet hoods may not slip over the outer ring of the filter.

Q: 7. 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: 8. Does it make sense to (can you ) add the Natural Density on top of this filter?

A: You can stack the filters. the polarizer should be on top. Keep in mind that the polarzer alone is about 2stop ND in addition to the unique properties it has to darken Sky, highlight Cloudes and reducing glare and reflection off glass, water and metal surfaces.

Q: 9. Is it OK to install on a lens already has the T* coating? What's going to happen if you double the T* coating?

A: Yes, it's fine. It would only be problematic if the T* coating itself had a distinct color cast, in which case the white balance would need adjusting. However, the coating itself improves light transmission pretty evenly across the spectrum, so you'll only notice the normal color cast of the polarizing layers -- which is pretty neutral on the Zeiss. I think only the Breakthrough Photography polarizers are (or may!) be more neutral.

Q: 10. Anyone using it with the auto focus on the Canon EF 100-400mm f/4.5-5.6L ISII USM Lens on a 90D body? Off brand CPL interferes.

A: Ice 77mm Slim Multicoated Circular Polarizer Filter does not interfere with any of the autofocus modes when conneting the Canon EF 100-400mm f/4.5-5.6L ISII USM Lens on a 90D DSLR camera. The camera and lens have a smooth transition even in tracking focus.
