Hoya G filter series are of the value range of filters. All these filters feature black matte aluminium satin finish frames which reduce reflections. Also Hoya G filters have double sided coatings to reduce the appearance of lens flare and ghosting caused by reflections.
The 77mm Hoya G series circular polariser filter specifically designed to allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds
The filters are ultimately designed for digital camera and digital SLR's as the multi-coatings prevents stray reflections due the susceptability of CCD and CMOS sensors to stray light. |
