Hoya Filter - UX CIR-PL II, 37mm

Hoya - UX CIR-PL II, features UV and CIR-PL filters. "UX" in the name stands for "User eXperience", meaning it denotes all the experiences users will gain through using them. Circular polarising (CIR-PL) filters are used to remove light reflections from surfaces. CIR-PL filters enhance saturation and contrast, and this is visible even in photos of the sky or tree leaves.

The construction of the Hoya - UX CIR-PL II includes a polarising film between the two pieces of glass, and the front ring is designed to rotate and position itself at the desired angle. The threading on the edges allows other filters and caps to be attached. The slim frame ensures there is no vignetting with wide-angle lenses.
