Focus APL-F002 37mm Circular Polarizer Filter for Mobile Photography

A circular polarizer filter engineered for mobile photography, the Focus APL-F002 cuts through glare and reflections to deliver crisp, vibrant images straight from your smartphone. Its 37mm high-definition optical glass rotates a full 360 degrees, giving you precise control over polarization for skies that deepen to rich blues and water that turns crystal clear.

Advantages

Built with aviation-grade aluminum and multi-layer anti-reflective coatings, this filter is both rugged and optically pure. The water- and oil-repellent surface shrugs off fingerprints and moisture, while the scratch-resistant glass keeps your shots sharp in any environment. A simple screw-on design pairs perfectly with the Focus APL-F001 lens kit or any universal clip system, so setup takes seconds.
