Designed to match the quality of Sony 's esteemed G Master series lenses, this 49mm T Circular Polarizer Filter helps to cut reflections and glare in order to enhance color rendering and tonal saturation. By filtering out light that has become polarized due to reflection from a non-metallic surface, this filter better enables photographing through windows or water and also reduces haze and UV rays to suit general landscape shooting. This filter features a ZEISS T anti-reflective coating to minimize surface reflections and glare between the filter and lens in order to maintain high contrast and color accuracy. Additionally, its slim profile lessens the likelihood of vignetting when used with wide-angle lenses.
