Cokin 77CPL 77mm Circular Polarizer Filter

The Cokin 77CPL Circular Polarizer is built around a simple goal: deliver effective polarization in the thinnest, lightest package possible. At just 4.5mm thick, it addresses one of the most common complaints with polarizing filters — vignetting on wide-angle lenses. Where thicker filters can intrude into the image frame and darken corners, the Cokin 77CPL's slim profile stays out of the way, making it suitable for focal lengths where other polarizers fall short. The exclusive high-transmission glass ensures that optical quality is maintained, with only a single f-stop of light loss.

Cokin's EVERCLEAR 5 multi-coating technology is applied to the filter surfaces, providing five layers of protection that reduce internal reflections, resist fingerprints and water spots, and guard against scratches from routine handling. In practice, the filter deepens blue skies, increases contrast between clouds and sky, saturates foliage colors, and cuts reflections from water and glass surfaces. The 77mm thread size fits a wide range of professional and enthusiast lenses, and full compatibility with standard lens caps means the filter can stay mounted as part of your everyday shooting setup.
