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.

but not for a wide angle outdoors, wider than about a 28mm 35mm full-frame equivalent. Anything wider and the sky gets wonky, as the sky doesn't have the same polarization across it - you'll wind up with a dark center and light edges, or vice-versa... Using mine on a Mamiya C3 normal 80mm lens.

Great and affordable

Works great for killing reflections or enhancing contrast on my Sony NEX-6!
