Helping to reduce reflections and glare, the Hoya 46mm Polarizer Filterfrom Hoya 46mm 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.

Q: 1. Can someone tell me the difference between this product and Tiffen's product?(a href= http://www.bhphotovideo.com/c/product/457543-REG/Tiffen_67LLPOL_67mm_Low_Light_Polarizing.html target= _blank http://www.bhphotovideo.com/c/product/457543-REG/Tiffen_67LLPOL_67mm_Low_Light_Polarizing.html/a)

A: The Hoya linear polarizing filter was designed for use on older film cameras - See the following description of a linear polarizing filter - (Two kinds of polarizing filters are the PL (Linear Polarizing) andPL-CIR (Circular Polarizing) filters which have the same effect ofreducing glare, however, there are differences in the way each worksin combination with your specific camera so it is important toresearch and choose the correct version of filter for your camera.Many of today's cameras use semi-silvered mirrors or prisms to splitthe light (a.k.a. beam) entering the viewfinder in order tocalculate exposure and focusing distance. PL filters can sometimesinteract with these light controlling devices to give unpredictableexposure or focusing. If your camera, whether auto or manual, isequipped with this kind of device, we recommend using a PL-CIR filter.Both types of filters allow you not only to remove unwantedreflections from non-metallic surfaces such as water, glass etc., butalso filter out atmospheric haze enabling colors to become moresaturated and appear clearer with a much sharper contrast.These effects will prove to be invaluable to photographers at anylevel of interest.)

Q: 2. What does turning the filter do? How can the effects be seen if it is used on a twin-lens camera?

A: Spinning the front of the Hoya 43mm Linear Polarizer Filter effects the level and angle of polarization. The only way to see the effect is to look through the lens that the filter is used on.

Q: 3. 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: 4. Does this circular polarizing filter have antireflective coatings?

A: No, that filter is not multi-coated.

Q: 5. Hi, I have a Zeiss 35mm biogon lens that I use most of the time which requires a 43mm filter. The problem is I cant find a 43mm R72 infrared filter. Would it be possible to use the 46mm?

A: With a step up ring from 43 to 46mm, you shouldn't have any problems. You generally do not experience vignetting (the dark corners) above around 24mms.

Q: 6. Can this lens be used with Panasonic LUMIX DMC-FZ70 16.1 MP Digital Camera with 60x Optical Image Stabilized Zoom and 3-Inch LCD (Black)?

A: You do not want to use a linear polarizing filter with today's Digital cameras. PL filters can cause unpredictable exposure or focusing problems. Your bets bet would be a circular polarizer.

Q: 7. 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: 8. Will this filter have a negative impact on autofocus in a mirrorless camera like the R5?

A: Linear polarizers usually have autofocus issues with DSLRs not mirrorless, so you shouldn't have a problem with the R5.

Q: 9. Will this fit the sigma 150-600 lens?

A: Yes, it will.

Q: 10. Does this remove refelxes in car glasses?//noelcom

A: Yes it will, but it may not be the correct filter if you are using a DSLR camera.How to select the correct Polarizing FilterTwo kinds of polarizing filters are the PL (Linear Polarizing) andPL-CIR (Circular Polarizing) filters which have the same effect ofreducing glare, however, there are differences in the way each worksin combination with your specific camera so it is important toresearch and choose the correct version of filter for your camera.Many of today's cameras use semi-silvered mirrors or prisms to splitthe light (a.k.a. beam) entering the viewfinder in order tocalculate exposure and focusing distance.
