The Haida 46mm Slim Pro II 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.

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, the glass includes 10 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.

2.5x filter factor reduces exposure by 1.3 stops.

Multi-coated to prevent internal ghosting and reflections.

Thin, aluminum-alloy filter ring helps to prevent vignetting while remaining durable and lightweight.

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

46mm 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.

Q: 1. Please can you tell me if this product is suitable to mount on the front of a DJI Phantom 2 Vision + ? Thanks!

A: This product is not recommended for use with the DJI Phantom 2 Vision+.

Q: 2. is this compatible with a canon rebel t6 camera18-55mm lens?

A: I bought for a nikon camera. I dont own a Canon Rebel 6 but from the specs of the 18-55 mm of your lens it wont be compatible. You need filter with a 58 mm diameter not 52 mm.

Q: 3. Does this lens filter work with Fuji X10 or X20 ?

A: This filter is not compatible with the Fuji X10 or X20 cameras.

Q: 4. Does this filter fits in NiSi V6 filter holder?

A: Yes, the Haida NanoPro CPL Circular Polarizing Filter (100 x 100mm) would be compatible for use in the NiSi V6 100mm Filter Holder.

Q: 5. can you leave the clear uv filter on and and the polarizer when needed?

A: Yes. If you so desire, you may leave the 82mm UV Slim PRO Filter connected to the filter threads on your lens at all times for use as a protection filter, and you may add the 82mm Circular Polarizer to the filter threads on the front of the 82mm UV Slim PRO Filter when polarization is needed.

Q: 6. will it fit canon 100mm usm macro lens

A: If your 100mm lens' diameter is 52mm, then it will work.

Q: 7. Is it compatible with the fujifilm x30?

A: The FUJIFILM X-T30 will work with any circular polarizer. The issue is filter size for the lens you are using. The typical lens for the camera is the XF 18-55mm f/2.8-4 R LM OIS Lens and that takes a 58mm filter. Here is a good one for that lens. Hoya 58mm alpha Circular Polarizer Filter B&H # HOCPA58.

Q: 8. is this filter compatible with a 30 mm f/1.4 sigma ?

A: Yes, the Luminesque 52mm Circular Polarizer and UV Slim PRO Filter Kit fit onto the Sigma 30mm f/1.4 DC DN Contemporary Lens.

Q: 9. Will this work on a Sony a6000 ??? Sometimes these Circular types will not work on particular Digital Cameras !!! Thank You !!!

A: This filter will work with any lens that has a 40.5mm diameter. Circular polarizers are compatible with digital cameras, however linear polarizers are not.

Q: 10. Where is it made?

A: It says Made in China on the lens ring.
