This Cavision 82mm Circular Polarizer Filteris designed for lenses with focal lengths of 70mm or less. It helps 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 82mm in diameter and is constructed from optical glass for maintained image quality.

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.

Filter ring can be rotated to adjust the intensity of the polarization effect.

Designed for lenses with focal lengths of 70mm or less.

Q: 1. Since this is a circular polarizer, does that mean the amount of polarization will be affected by the amount you rotate it?

A: Yes as you rotate it inside the filter holder purchased separately you set the amount of polarization. But you would rotate a linear polarizer the same way to set the polarization.

Q: 2. Is this polarizer scratch-proof?

A: The Sony 82mm T* Circular Polarizer Filter is not published by the manufacturer as being scratch-proof.

Q: 3. Can this filter attach to the UV filter already on the lens or is it best to use one or the other?

A: Most UV filters have front filter threads. So you could attach the ZEISS 67mm Carl ZEISS T* Circular Polarizer Filter to the front of most UV filters.

Q: 4. What is the filter factor, i.e. how many stops of light are reduced?

A: The filter factor of the Sony 82mm T* Circular Polarizer Filter is 1.6x, i.e., 3 stops of light are reduced.

Q: 5. Will the stock Canon RF lens caps work for this, or can you recommend one that is sure to work?
