This K&F Concept Slim Circular Polarizer Filter 62mmfrom K&F Concept Slim Circular Polarizer Filter 62mmis a 62mm multicoated glass circular polarizing filter that helps reduce reflections and glare by filtering out light that has become polarized due to reflection from a nonmetallic surface. The light from the sun 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 directionally polarized light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.

This filter is constructed from Japanese optical glass for clarity as well as color fidelity, and it features multicoating to prevent internal ghosting and reflections. It is made with an aluminum alloy filter ring that can be rotated to adjust the intensity of the polarization effect. The slim design reduces the potential for vignetting when used with wide-angle lenses.

Related Questions and Answers

Q: 1. How much stops of light does it reduce?

A: Unfortunately, a filter factor is not provided by Nikon for this CPL.

Q: 2. Is it stackable

A: No, the K&F Concept Nano-X ND2-32 Variable Fader & Circular Polarizer HD Green Coated Waterproof Anti-Scratch Japan Optics Filter (77mm) does not have filter front threads.

Q: 3. Hoya 82mm HD3 Circular Polarizer Filter and Hoya 82mm EVO Antistatic Circular Polarizer Filter. Which one is better and why? Why HD3 so expensive? Is the photos will be different?

A: The HD3 has harder coatings, and uses a higher quality polarization film.

Q: 4. What is the recommended cleaning for this polarizer?

A: You may use a product such as the Pancro Professional Lens Cleaner (4 oz), B&H # PAN001 and a Sensei Microfiber Lens Cleaning Cloth (Gray), B&H # SECCMF77G to clean this filter. https://bhpho.to/2Vlp07b https://bhpho.to/2MkTd27

Q: 5. Is the .3 stop light loss number in the specifications accurate?

A: I suspect that there is some semantics involved. However, I find the in my terms the factor is 1.3. By this I mean for example: holding the shutter speed constant, I get a reading of f9 without the filter, with the filter on and adjusted for maximum effect it will require a aperture of f5.6 for an equivalent exposure. I was mislead by the point three as well, but it is still better than the 2.5 or a bit more that conventional filters of this type yield.Hope this helps.

Q: 6. Is there an adapter so the 112 mm circular polarizer can be used on other lenses, such as 77 mm?

A: Unfortunately, a step down ring from 112-77mm is not currently offered.

Q: 7. Does this filter come with a case?

A: Yes, a storage case is included.

Q: 8. Does this have front end filter threads such that a Lee adaptor can be put on?

A: This has front end threads

Q: 9. How does the Hoya Brand compare to Heliopan or Sony circular polarizers?

A: Hoya makes a very good filter and is comparable to Sony and just under Heliopan's quality.

Q: 10. Can I put it on a sigma 30 mm lens?

A: In theory you could with a step down ring, but you'll get vignetting on the edges. I'd recommend getting the correct 52mm filter.
