Hoya A-7725A-GB Overview

This red filter is ideal for strong contrast improvement since it absorbs green and blue completely and enhances red. Clouds are dramatically improved almost to the mood of a thunderstorm. It is more effective in cutting through haze, and moonlight effects are easily accomplished. It is also suited for infrared photography. Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Filter factor is 8 (+3 stops)
