The Hoya Nano filter is a circular polarizing CPL filter with an HD film that offers 25% greater light transmittance than standard polarizing films used in photographic filters. Its effect on color balance, contrast, and sharpness is limited to its polarizing effects. The increased transmittance allows for faster shutter speeds.

The 16-layer coating is stain-resistant and repels water and oil, making everyday maintenance easier. Its surface is 200% more scratch-resistant than standard coatings. The slim frame has a front thread for attaching lens caps and other filters, while the press-mount technology holds the glass securely in place.
