The PGYTECH CPL-ND8-ND16 filter set for Osmo Pocket contains 2 gray filters and a polarization filter, with which you can record images in various situations. With the ND8 gray filter you correct 3 stops lightly and with the ND16 filter you correct 4 stops. This allows you to use slower shutter speeds without overexposing images. This produces smooth video images. The CPL polarization filter prevents unwanted reflections and glare in water or windows. In addition, the polarization filter increases the contrast and the color intensity of your images. Thanks to the special coating, the filter is oil, water, dirt and scratch resistant. The design is low in weight, making your Osmo Pocket hardly heavier. Via a simple click system you attach the filter to the lens of the camera.
