High Transmission Circular Polarizer MRC Nano Filter for enhanced color purity and saturation Rotating filter mounts allow visible control of polarization effect through viewfinder or monitor display Reduces reflections from non-metallic surfaces like water, glass, and glossy paint Compatible with nearly all modern cameras using beam splitters for TTL exposure metering or autofocus High Transmission Circular (HTC) multiplier factor between 2 to 3, equivalent to 1 to 1.5 f-stops Ideal for landscape photography, achieving maximum polarization effect at a 90-degree angle to the sun
