Cavision FTG4X4PLC overview

  • 1Description

The Cavision 4 x 4" Circular Polarizer Filter 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 4 x 4" / 101.6 x 101.6mm and is constructed from 4mm-thick optical glass.

This filter 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.

    Cavision FTG4X4PLC reviews

    4 x 4" Circular Polarizer Filter is rated 4.0 out of 5 by 3.
    Rated 5 out of 5 by from Top notch product!!! I purchased this because I could not afford the more expensive brands. I figured I was going to get what I paid for and have some regrets but to my amazement , it turned out to be very high quality glass!!! This heavy quality glass even comes nicely wraped on all four sides with a rubber seal which makes it easier to handle and protects against chips. It even comes wraped in a large velvet cloth and a impressive Velcro case that is padded. My photos are so much better now with day shots and it beautifully removes reflection in the water and really brings out the blues in the sky. This glass was worth every penny. I plan to buy more glass from this company soon!!!

    Rated 3 out of 5 by from Good glass, weak polarizing I tested this filter against the Lee Circular Polarizer. At a fraction of the price I was hoping this filter would do the job. However in the end I went with the Lee. This filter was very sharp, a great piece of glass. However, it didn't give as much contrast in the sky because it didn't darken the blue as much as the Lee.
