HOYA UX CIR-PL 40.5mm

The series name "UX" refers to "User eXperience" (user experience, experience) that users have when applying these filters and everything that goes with it. The choice of the UX series name also aims for the manufacturer to offer users more pleasant personal experiences through all activities related to photography.
The UX CIR-PL filter can be used with both film and digital cameras. Effectively controls light reflection from non-metallic surfaces, such as water and glass, and at the same time enhance color saturation and contrast.

The polarizing filter structurally contains a polarizing film between two glass sheets, and the frontal side of the filter socket can be rotated, thus giving the opportunity to adjust the polarizing film at the desired angle. The threaded filter socket enables the connection of additional filters and a protective lens cap. The flat (thin) filter holder of the UX CIR-PL ensures that vignetting does not occur even with wide-angle lenses.
