Heliopan 37mm Circular Polarizer SH-PMC Filter (703746)

Heliopan High-Transmission Circular Polarizer Slim (SH-PMC) Filter

Delivers maximum polarization with minimal light loss, turning ordinary shots into vibrant, high-contrast images. Ideal for landscape and outdoor photography, it deepens blue skies, enhances clouds, and eliminates reflections on water and glass—while remaining fully compatible with autofocus and auto exposure systems.

Made from premium Schott optical glass and mounted in a black slim brass ring with index markings for repeatable settings. The advanced SH-PMC 16-layer multi-coating (8 layers per side) provides exceptional flare reduction, durability, and resistance to dust and moisture. High-transmission design passes 98.8% of light with only 1-stop exposure loss and no color shift. No front threads to prevent vignetting on wide-angle lenses.
