The Tiffen 4 x 5.65" Linear Polarizer Filter helps 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.

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. It is non-coated and delivers approximately 40% average light transmission.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch.

Q: 1. Hi There, can you please tell me, could this also work on a 4 x 4 matte box?

A: No this is for 4x5.650 with 5.650 being the horizontal dimension so will not fit in 4x4 slot. Suited to ARRI LMB 5 or LMB 15 or LMB 25 amongst others.

Q: 2. 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: 3. How many slots does this filter take? Does this also have a cool/warm fx when facing towards camera?

A: This has 1 slot with no color shift.

Q: 4. I have a Nikon Coolpix L340. I am aware that it's lens is 35mm. Is this polarizer applicable to that particular camera?

A: The Nikon COOLPIX L340 digital camera does not have filter threads on the lens. So you cannot use any filters on this camera.

Q: 5. Is this compatible with Bright Tangerine Misfit Kick?

A: The NiSi Cinema 4 x 5.65" True Color Rotating PL Linear Polarizing Filter is compatible with any standard matte box tray.

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. What makes this not compatible with Titla? I have the MB-T12 and it says trays are compatible with Arri and Panavision trays which this will work with.

A: According to the manufacture of this product it is not compatible with Redrock Micro and Tilta Matte Boxes. The exact reasons are not specified, however it more than likely will have to do with the shape of this tray not fitting those Matte Boxes well.

Q: 8. Does the ND/Pol filter push the Mavic Mini over the weight limit of 250kg?
