The Tiffen 52mm Warm Linear Polarizer Filter can be applied to create a warm cast over an entire image while helping 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.

The warming effect of this filter can be obtained under daylight when this filter is used on a film camera system with daylight film installed, or on a digital camera system with its daylight white balance setting selected. This filter's overall coloration reflects a mired shift value of +45.

A linear polarizer differs from a circular polarizer in that it does not contain an additional quarter wave plane. The addition of a quarter wave plane is to circularly polarize 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, in-camera 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 recommended when not using in-camera exposure metering or autofocus, is non-coated, and has approximately 40% average light transmission. It 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.

Related Questions and Answers

Q: 1. Can I use this filter on a Lee filter system holder?

A: There are two industry standard nominal filter thicknesses: 2 mm and 4 mm. The Lee holder, while normally set up for 2 mm, can, with the addition of longer screws, can accommodate 4 mm filters as well.

Q: 2. Will this fit in the NiSi V5 pro holders?

A: From the NiSi V5-PRO manual: The filter holder can be used only with square filters with a width of 100 mm and a thickness of 2 mm.

Q: 3. I am interested in purchasing filters: polarized filter as well as a ND filter. There are so many to choose from - any suggestions?Hoya vs B&W ? What specifications should I compare? I am prepared to spend the extra money for the quality that best suits my current (beginner) and future needs. Camera Nikon D750 lens Nikkor 24-120.

A: I use both Hoya and B&W filters and are equally satisfied with them. Don't use polarizing filters for wide angle lenses.

Q: 4. Will this fit on canon EF 50mm f/1.8 STM lens?

A: The Canon EF 50mm f/1.8 STM Lens accepts49mm filters, including this one.

Q: 5. 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: 6. Is this filter multicoated?

A: This filter comes with Hoya's standard coating.

Q: 7. WHAT OTHER BRAND 105mm CPL FILTERS CAN BE FITTED TO LEE 105mm CPL ADAPTER ONTO LEE 100mm FILTER HOLDER?

A: As long as you have this 105mm adapter on your Lee foundation kit: https://bhpho.to/2cujqJ5 You will be able to use any filter that has 105mm threads such as this Haida 105mm circular polarizer.

Q: 8. Can I screw on and attach a metal hood to this polarizer?

A: The, the front of this filter is threaded and can accept any other 49mm sized hood or filter.

Q: 9. What size lens cap fit this filter?

A: A 48mm lens cap will fit this filter.

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. 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.
