Helping to reduce reflections and glare, the Hoya 55mm Polarizer Filterfrom Hoya 55mm Polarizer Filterfilters out light that has become polarized due to reflection from a non-metallic surface. By filtering this light, a noticeable increase in the saturation of skies and foliage is possible, as well as the ability to produce clearer imagery when photographing in hazy conditions. The filter is constructed from optical glass and is mounted within a durable, lightweight aluminum ring that has a hard anodized finish to guard against wear.

A linear polarizer differs from a circular polarizer in that it does not support the use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

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.

Optical glass construction maintains image clarity.

Aluminum filter ring is both lightweight and durable and features a hard anodized finish to guard against scratching and wear.

Related Questions and Answers

Q: 1. Is this filter multi-coated? What is the difference between this filter and the Hoya 43mm NXT Circular Polarizer Filter (B&H # HOCPN43 MFR # A-NXT43CRPL)?

A: This polarizer is not multi-coated. The difference between this filter and the NXT filter is that Hoya NXT filters have over 97% average light transmission, and are constructed from heat-resistant, high-transparency optical glass.

Q: 2. Anyone used this on the Venus Laowa 17mm f/4?

A: It will fit perfectly on the Laowa 17mm f/4 GFX Zero-D lens, but, with such a wide focal length, there's a possibility some vignetting may occur when using this filter.

Q: 3. Is the Hoya HRT a thin profile filter?

A: No.

Q: 4. Will this fit the sigma 150-600 lens?

A: Yes, it will.

Q: 5. will this one fit on new sony FE 20/1.8 G ???? or do i need the slim version for 20mm ?

A: A slim filter would be recommended when using a lens that is 28mm or less on a full frame camera.

Q: 6. Will this filter fit the DJI Inspite 1 Camera?

A: It can fit but should not be used. The weight of the filter will throw off the calibration and make the Gimbal not function properly.

Q: 7. Is the Hoya HRT Circular Polarizer multi-coated?

A: The Hoya HRT Cir/Pol - UV combo filter is a non-coated filter.

Q: 8. Is this a better polarizing filter than the B+W 77mm XS-Pro Kaesemann High Transmission Circular Polarizer MRC-Nano Filter at half the price?

A: What you are paying for is quality. Hoya is one of the best companies making filters. With this one you getting all the best features Hoya can produce. The quality of the ring, the glass, the foils that make up the Polarizer, the works. The B+W, on the other hand is the finest they make in this size. Honestly, without comparing side by side, it is hard to make a determination. I suspect both will have outstanding performance and build quality and the in the long run, you will not lose with either.

Q: 9. I plan on using the filter on a drone, and the gimbal on the drone requires a weight range for filters to maintain balance. Does anybody know how much the filter weights (in grams, if possible)? Thanks!

A: .9 oz, according to my kitchen scale. Or 25 grams.

Q: 10. Would this circular polarizer cause vignetting on the low end of a 15-35mm zoom?

A: Due to its relatively thin profile, it should not cause vignetting on a 15-35mm. However, in the event there is some, it would be very, very minor.
