Urth CPL Polarizing Filter for Square Filter Holder Plus+

This Urth CPL Polarizing Filter is built for Urth's Square Filter Holder System rather than as a screw-in filter, and it's part of Urth's Plus+ range with heavier nano-coating than their base line.

• Function: Cuts out 99.9% of reflected, polarized light from water, glass, and other non-metallic surfaces, revealing bolder color in the image.
• System Fit: Made specifically for use with the Urth Square Filter Holder system, not as a direct screw-in filter.
• Coating: Plus+ range filters carry 20 layers of nano-coating, which makes cleaning easier and adds protection against water, oil, and scratches.
• Optical Performance: The extra coating layers also give a higher maximum light transmission and a more consistent transmission curve, for sharper images and finer color.
