Overexposure is your worst enemy whenever you shoot under intense sunlight. However, the Okko Pro Circular Polarizer Filter 55mm allows you to suppress glare to capture clear and colourful images without unwanted reflections.

The filter's aluminium alloy frame gives it a robust look. Meanwhile, its ultra-thin frame minimizes vignetting when capturing wider angles. The easy to clean Okko Pro Circular Polarizer Filter 55mm will fit perfectly with your standard lens cap.
