SmallRig 6733 Clip-On CPL Filter for iPhone 18 Pro / 18 Pro Max

SmallRig CO-F1 6733 Clip-On CPL Filter

This circular polarizing filter attaches to an iPhone 18 Pro or iPhone 18 Pro Max in seconds, without an additional mounting base. Its flexible silicone clip provides a secure fit with most phone cases that have a sufficiently large cutout around the rear camera lens backplate. Check that the case cutout measures at least 61.5 × 37.5 mm before use.

The polarizing glass reduces reflections from water, glass, and metal surfaces, helping reveal detail obscured by glare—for example, fish below the water’s surface, products behind shop windows, and paintwork texture. Turn the front ring to adjust the polarization effect one-handed while shooting, allowing you to fine-tune reflections and contrast without stopping recording. The dual-layer design keeps MagSafe access clear.
