Key Features
- Linear Polarizer Filter
- 2.5x Filter Factor, +1.3 Stops
- Helps to Eliminate Reflections and Glare
- Reduces Haze in Landscapes
The Tiffen 6 x 4" 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.

Since you are out of stock on the Tiffen 49mm ...
Since you are out of stock on the Tiffen 49mm Cir. Pol., can I use a linear polarizer instead on a mirrorless camera? My recollection is that Cir. Polarizer was developed to compensate for the effect of the mirror on light measurement in the camera, and if so, then shouldn’t be necessary for mirrorless camera.
Yes, a linear polarizer will have no effect on metering or autofocus (PDAF or CAF) in a mirrorless camera, which historically would cause metering and autofocus issues in cameras with mirrors or single-translucent lenses (SLTs).

question
Hello,What is the difference between this product and the Tiffen 82mm Circular Polarizing Filter?Thank you,Nansen
A linear polarizer only differs from a circular polarizer in that it does not contain a quarter wave plane that enables use of auto focus and exposure features. It is generally advised to not use linear polarizers with digital cameras, as digital SLRs are dependent on internal mechanisms to determine focus or metering.

Is it possible to use this filter and the Tilta Mi
Is it possible to use this filter and the Tilta Mirage Pro Matte Box VND filter at tye same time?
The Tiffen 4 x 5.65" Linear Polarizer Filter cannot be stacked with a VND filter. Stacking a linear polarizer with a VND filter will cause cross-polarization and color shifting. To have polarization with a VND, you would need a combination VND/PL filter, or you could use static ND filters stacked with a polarizing filter.

question
Whats the difference between linear and circular polarizers? Im using a matte box with a rotatable 4x4 filter tray. Thanks.
Both a linear polarizer and circular polarizer will give you similar results although a circular polarizer should be used on cameras with beam splitting metering systems commonly found on auto focus SLR's/DSLR's.
