The Cavision 150mm Circular Polarizer Filterhelps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.

This filter measures 5.91 x 5.91" / 150 x 150mm and is constructed from 2mm-thick optical glass.

This filter is compatible with the LEE Filters SW150 Filter Holder and is designed to be used with 35mm lenses up to 70mm in focal length or that offer an equivalent angle of view depending on the sensor size of the camera.

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Arrange and filter directionally polarized light perpendicularly to the reflected light allowing for the absorption of much of the light.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

Strongest effect when used at a 90° angle from the sun.

Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features.

Constructed from high quality optical glass.

Q: 9. This a square circular polarizing filter. For those who bought this, how do you adjust it while using it with other filters such as graduated neutral density and still maintain the right composition with the position of the graduated filter?

A: Unfortunately with this system there is no option to rotate a polarizer independently of a grad filter. I would recommend getting the Nisi holder for 150mm filters. As far as I know, they are the only brand that has round 150mm polarizers for their system and your lee filters will fit in the slots.
