Fully encased filters with a custom CNC aluminum frame in the industry standard size of 4 x 5.65, compatible with any matte box. These filters provide high-quality edge protection against clamps and drops from the matte box. The laser-sharp filter markings are located on the front and top of each filter. They are 50% lighter than traditional 4 x 5 filters, making them perfect for gimbal applications. The aluminum frame offers unparalleled glass protection, safeguarding your glass from matte box clamps, falls, fingerprints, and more. You no longer have to worry about where to place the device during a filter change, as you can set it on any flat surface without damaging the glass. The 100% visible filter engravings on the top and front of the frame allow for quick identification of the filter strength. This way, you can quickly see which filter you need, grab it, and start shooting. Thanks to the aluminum frame, you can easily install and remove the filters without leaving fingerprints on the glass. The PolarPro x Motion Clubhouse 4 x 5 filters are designed to ensure flawless color accuracy, allowing you to capture the world through the camera just as you see it in real-time.
