LEE Filters 105mm Circular Polarizer Glass Filter CIRCPLGLS105

The LEE Filters CIRCPLGLS105 is a professional-grade 105mm circular polarizer crafted as a frameless optical glass element. Unlike screw-in polarizers that add bulk and require dedicated threads, this filter is engineered to drop directly into the LEE SW150 holder system or compatible 105mm adapters, making it an indispensable tool for landscape and architectural photographers who demand precise control over reflections and glare.

Highlights

• 105mm circular polarizer for LEE SW150 and compatible holders
• Frameless, multi-coated optical glass construction
• Reduces reflections and glare while enhancing color saturation
• Rotatable design for adjustable polarization effect
• Approximately 1.5 to 2 stops light loss (filter factor 2x-4x)
• Professional-grade optical quality

In daily use

When shooting waterfalls, windows, or wet foliage, the CIRCPLGLS105 cuts through unwanted specular highlights, revealing deeper tones and richer textures. Rotate the glass within the holder to fine-tune the effect—from eliminating reflections entirely to subtly boosting contrast. The 7mm thickness and frameless profile minimize vignetting even on ultra-wide lenses, while the multi-coated surfaces help suppress flare and ghosting in backlit scenes.
