THK has recently rolled out a new HOYA HRT circular polarizer filter that uses a newly developed High-Rate Transparency film to pass 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.
