This 6-stop, 62mm NiSi Solid ND & Circular Polarizer Filter 62mm 6-Stopcombines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 64x filter factor provides a 6-stop exposure reduction. Its 1.8 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed without overexposing your image By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Simultaneously, this filter can help 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 non-coated and is constructed from optical glass for clarity and features an aluminum alloy filter ring that can be rotated to adjust the intensity of the polarization effect.

Related Questions and Answers

Q: 1. Would this filter give me rich and colorful results when doing street photography, and if so, how many stops should I go for so that I dont have to change the filter too often even if it gets dark, 3, 4 stops?... or should I go for a polarizer one? Thanks

A: Yes, it will clean up your images by saturating colors and increasing contrast. I would just go with a polarizer that would cut out about 1-2 stops.

Q: 2. Hello! Does this filter have front threads (to attach a lens cap)? Thanks!

A: Yes. 77mm front filter threads allow for use with other filters or a lens cap.

Q: 3. Can you use a lens hood with this? I am new to photography and can't seem to find one that would fit in or over this

A: The front of the K&F Concept Nano-X Circular Polarizer plus Variable ND2-ND32 Filter (58mm) is 62mm so you can attach a 62mm hood such as this: https://bhpho.to/3gdgVNq

Q: 4. would this work with the tilta mini matte box if I added an extension ring in there?

A: Yes, It comes with an 82mm adapter ring.

Q: 5. Why the green coating on the filter?

A: It aids in the reduction of glare that the filter could encounter according to K&F.

Q: 6. will PolarPro 82mm ND1000 QuartzLine Circular Polarizer Filter (10-Stop) cause vignetting at 15mm of Canon RF 15-35 F/2.8 lens?

A: The PolarPro 82mm ND1000 QuartzLine Solid Neutral Density 3.0 and Circular Polarizer Filter (10-Stop) will not vignette at 15mm on the Canon RF 15-35mm f/2.8 L IS USM Lens (Canon RF).

Q: 7. Does this have threads on the front side too? I'd like to attach a lens hood

A: Yes, this does have front filter threading. You can attach a lens hood to this filter.

Q: 8. Seems thick. Will it vignette? Depending on lens I suppose. Also, will it interfere with lens hood?

A: If your lens is wider than 24mm (full frame), then yes it will probably vignette. It would most likely interfere with the hood.

Q: 9. I have a Canon 24-105mm f4L(77mm). I already have a 77mm protective filter on it; with threads, so I can stack another filter. What size ND filter should I order?

A: Protective filters have the same size front and rear threads so a 77mm variable ND would be recommended.

Q: 10. Curious if this ND/PL stacked with a Tiffen Black ProMist on a 24mm lens will cause vinette problems (@f/1.4 thru f/4)? I'm thinking it likely will and might then go for non PL version as it looks slightly thinner? Cheers if anyone's already test this out?

A: If you use this on a full-frame camera, you would be likely to have some vignetting. On a crop-sensor camera, it would be less likely.
