The Tiffen 105mm Coarse Thread 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. Hi. The native Canon EF-S 24mm f/2.8 STM lens cap doesn't hold up very well on this glass. Tell me, maybe there are more suitable covers for this filter when it is not used?

A: You can try the Sensei lens cap; https://bhpho.to/2SgGWyK

Q: 2. Does this come with a filter pouch?

A: Yes, an individual filter pouch is included in the box with Lindsey Optics 138mm Brilliant Rota-Pol Circular Polarizer for 4 x 5.65" Cine Matte Boxes.

Q: 3. With a mirrorless Micro-4/3rds camera, do you need to use a circular polarizer? Or will a linear one be effective?

A: Circular polarizer filters are recommended for use if you will be using autofocus to focus your lens, as linearly-polarized light can confuse autofocus sensors and cause autofocus errors. However, if you will be focusing your lens manually, you may use a linear polarizing filter.

Q: 4. It says usually ships in 2 to 3 days, also says out of stock. will it shop in 2 to 3 days or not?

A: Add the item to the cart online to calculate shipping to your address. For up to date stock questions you can email sales@bhphoto.com

Q: 5. Does this have front threads for filter stacking?

A: Yes, the Hoya 82mm Moose Peterson warm circular polarizer has front filter threads for stacking additional filters. Please be aware that due to the thickness of this filter, stacking more filters could potentially lead to vignetting issues with certain lenses (usually wider-angle lenses).

Q: 6. Will this work with the Mirage matte box?

A: The Lindsey Optics 138mm Brilliant Rota-Pol Circular Polarizer for 4 x 5.65" Cine Matte Boxes is compatible with the Mirage matte box.

Q: 7. There will be vignetting when used with Zeiss Distagon 15mm?

A: This filter will not vignette nor will that lens.

Q: 8. Will this work without vignetting with a 14mm Fuji lens that equals 21mm in full frame?

A: There should not be any vignetting, but this will still depend on the exact lens you are using. For further assistance with this question feel free to email askbh@bandh.com.

Q: 9. Thickness? Need 30.5 mm polarizer that will fit in filter drawer of 600 mm catadioptric. Filter needs to be 7 mm thick.

A: Heliopan 30.5mm Linear Polarizer Filter is 6mm thick.

Q: 10. I just watched a video on YouTube where the gent says there are NO filter threads inside but the specs here list that there are?

A: I contacted Formatt-Hitech with your inquiry. They state that the Formatt Hitech 77mm Firecrest SuperSlim Circular Polarizer Filter, B&H # FOFCSSCP77, has 77mm front filter threads. They state you may stack multiple threaded filters onto each other as long as they all have the same 77mm filter thread diameter size.
