C-PL Circular Polarizer Multicoated Multithreaded Filter (67mm) - Slim

Our review of the C-PL (Circular Polarizer) Multicoated filter for the Nikon COOLPIX P900 finds it best suited to photographers and videographers who need a compact, rugged polarizer that reduces reflections while keeping weight and vignetting low. The filter's slim design and multithreaded metal ring make it easy to stack or mount additional filters, and the stated light transmission change of between 2.3 and 2.8 (about +1.3 stops) gives a predictable, modest exposure shift. In short, this review highlights a practical, well-built polarizer for field use and travel shooting.

Key Features

• Circular polarizer: Reduces reflections and increases color saturation for clearer skies and richer foliage in both photography and video.
• Light transmission change: Between 2.3 and 2.8 (approx. +1.3 stops) gives a consistent exposure adjustment to plan for during shooting.
• Rugged metal filter ring: Black finish metal construction resists wear and handles frequent mounting and removal on the COOLPIX P900.
• Slim design: Minimizes vignetting on wide or long focal lengths so the filter is usable across more compositions without darkened corners.
• Multicoated glass: Improves contrast and reduces flare for cleaner images in bright or backlit conditions, useful for both stills and video.
• Multithreaded mounting: Allows additional filters or lens accessories to be stacked on top, adding flexibility for creative workflows.

Who It's For

The C-PL 67mm is aimed at photographers using the Nikon COOLPIX P900 or other lenses that accept 67mm filters who want a tough, slim circular polarizer for landscape, travel, and outdoor portrait work. Its multicoated glass and slim profile make it a good pick for shooters who frequently switch between wide and telephoto framing and need to avoid vignetting.

Serious studio shooters or those requiring precise optical metrics for large-format glass may prefer a higher-end branded option with detailed lab data, but for field use and casual pro assignments the C-PL delivers the practical benefits of polarization, durability, and stackable threads at a sensible value.

Pros & Cons

Pros

• Durable metal filter ring provides solid handling and long-term reliability in outdoor conditions.
• Slim profile helps prevent vignetting at wide angles and when using long focal lengths.
• Multicoated, heat treated glass improves contrast and reduces unwanted reflections for clearer shots.
• Multithreaded design supports stacking additional filters or accessories without extra adapters.

Cons

• The specified light reduction of ~+1.3 stops requires exposure compensation planning for some scenes.
• Limited to lenses that accept 67mm threads, so buyers with different thread sizes must use step rings.
