Hoya YYP4243 43mm UX II CIR-PL Filter

The Hoya UX II CIR-PL 43mm filter is engineered to tackle one of the most common challenges in outdoor and product photography: unwanted reflections and washed-out colors. By polarizing incoming light, it selectively blocks glare bouncing off non-metallic surfaces such as water, glass, and foliage. The result is deeper blue skies, richer greens, and cleaner shots through windows or near reflective surfaces. Its 10-layer HMC-WR (Hard Multi-Coating, Water Repellent) treatment on both sides of the glass reduces internal reflections that cause flare and ghosting, while the water-repellent top layer makes cleaning easier and helps the filter perform in damp conditions.

Built with a low-profile aluminum frame, the UX II CIR-PL is designed to sit close to the lens element, reducing the chance of vignetting when used on wide-angle lenses — a common issue with thicker filter frames. The smooth-rotating ring allows quick adjustment of the polarizing angle without fighting stiff threads. For photographers working with 43mm-threaded lenses who want a meaningful optical upgrade over basic polarizers, the UX II line offers a practical balance of build quality, coating technology, and slim form factor.
