The Formatt-Hitech 39mm UltraSlim 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 is constructed from optical glass for maintained image quality and is set in an aluminum filter ring. The UltraSlim ring measures 4.5mm-thick and its slim design helps to minimize the likelihood of vignetting. This filter does not feature front threads in order to maintain the thinnest design possible for enhanced use on wide-angle lenses.
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° from the sun.
Optical glass is used in order to maintain clear image quality with high contrast and color fidelity.
The aluminum alloy UltraSlim filter ring measures 4.5mm-thick and does not feature front threads in order to maintain a slim profile that minimizes the likelihood of vignetting with wide-angle lenses.
