Overview
The Heliopan High-Transmission Circular Polarizer Slim (SH-PMC) is designed to deliver maximum polarization with minimal light loss, producing high-contrast, vibrant images while maintaining excellent optical clarity. It is ideal for landscape and outdoor photography, enhancing blue skies, boosting cloud definition, and removing reflections from water, glass, and other non-metallic surfaces. The filter remains fully compatible with autofocus and auto exposure systems.

Constructed from premium Schott optical glass and housed in a slim brass ring, it is engineered to reduce vignetting on wide-angle lenses by eliminating front threads. The indexed rotating mount allows precise and repeatable polarization control. The advanced SH-PMC 16-layer multi-coating (8 layers per side) provides strong flare resistance, improved durability, and protection against dust and moisture. The high-transmission design allows approximately 98.8% light throughput with only about 1 stop of light loss and no color shift.
