Nikon 2236 58mm Circular Polarizer II Camera Filter

The Nikon 2236 58mm Circular Polarizer II is a screw-on lens filter built to reduce unwanted reflections and enhance color saturation directly at the point of capture. When photographing landscapes, the filter deepens blue skies and makes clouds more dramatic by cutting through atmospheric haze. When shooting near water or through glass, rotating the outer ring progressively eliminates surface reflections, revealing what lies beneath or behind. These effects are achieved optically and in real time, saving significant post-processing effort and producing results that are difficult to replicate with software alone.

Constructed with multi-coated glass, the Nikon Circular Polarizer II minimizes internal reflections and flare that can degrade image quality — an important consideration since adding any filter element in front of your lens introduces potential optical compromises. The 58mm thread size is common across many popular Nikon and third-party lenses, and the filter is compatible with the HN-CP17 lens hood for photographers who want both polarization and flare protection. As a circular polarizer rather than a linear type, it maintains full compatibility with autofocus systems and through-the-lens metering found in modern DSLRs and mirrorless cameras. The filter is manufactured in Japan, consistent with Nikon's reputation for precision optical components.
