Hoya 55mm HRT Circular PL Polarizer Multi-Coated Glass Filter with:
The Hoya HRT Circular Polarizing (Cir-PL) Ultraviolet (UV) Multi-Coated Filters eliminate reflections from nonmetallic surfaces and increases contrast and color saturation such as water and glass.
This filter uses a newly developed High-Rate Transparency film that passes more visible light through the filter while still filtering the same amount of polarized light. The HOYA HRT circular polarizer filter transmits as much as 25% more light through the polarizing film giving the photographer about 1/3 stop more light than a standard circular polarizer.
Hoya HRT Cir-PL UV filters are optimized for use with digital SLR cameras, but they are also perfect for traditional 35mm SLR applications, including black and white photography.
