Gain more control over the shutter speed on select iPhone and Pixel phones using the Iris Mobile Filter System from PolarPro. Included is an ND8 filter, an ND16 filter, and an ND32 filter. The ND8 filter reduces the amount of light entering the lens by three stops, while the ND16 provides a four stop reduction and the ND32 filter provides a five stop reduction. All of this allows for the use of slower shutter speeds in brightly lit environments for both still photography and video. When used for still photography, images can be created with varying levels of motion blur. When shooting video, these filters can be used to set the shutter speed at twice the frame rate, thus creating a more cinematic look.

These filters are built using Cinema Series glass that are encased in a lightweight aluminum frame and provide sharp images with neutral colors. Each filter may be used with or without a phone case, and are compatible with the iPhone X, XR, XS, XS Max, 7 / 8 Plus, and 6 / 7 / 8, and well as the Google Pixel 2 and 2 XL. Protection is provided by a limited lifetime warranty.

Please note that manual shutter speed control requires a third-party app. Also, the iPhone 7 Plus, 8 Plus, and Pixel 2 XL require a counterweight for use with the Osmo Mobile and Osmo Mobile 2.
