Hoya Y7POLC067 67mm HRT UV Circular Polarizing Filter

The Hoya 67mm HRT UV Circular Polarizing Filter is a dual-function filter that combines circular polarization with UV absorption in a single piece of glass. Its defining feature is Hoya's High-Rate Transparency polarizing film, which allows up to 25% more visible light to pass through compared to conventional circular polarizers — translating to roughly 1/3 stop more light reaching the sensor. This makes it particularly useful in situations where maintaining shutter speed or working in lower light matters, as the brighter transmission reduces the exposure penalty that typically comes with using a polarizer.

The circular polarizing function works as expected: rotating the front ring lets you control the reduction of reflections and glare from non-metallic surfaces such as water, glass, and foliage, while also deepening sky contrast and color saturation. The integrated UV absorption helps cut atmospheric haze, improving overall clarity in outdoor and landscape photography. The slim aluminum frame is built to minimize vignetting on wide-angle lenses, and the multi-coated optical glass with black-rimmed edges works to suppress ghosting and internal reflections. For photographers looking to consolidate their filter setup without sacrificing light, the HRT offers a practical combination of polarization, UV protection, and higher-than-average light transmission in one filter.
