C-PL Circular Polarizer Multicoated Multithreaded Filter 43mm - Slim

In this review of the C-PL Circular Polarizer Multicoated 43mm, the bottom line is simple: it is a compact, well-built polarizing filter aimed at photographers and videographers who need cleaner reflections and richer color without bulk. The reviewer found it best for small mirrorless and compact cameras like the Panasonic LUMIX DMC-LX100 where a slim profile matters. Its multicoated, heat treated glass and multithreaded metal ring make it a durable everyday filter that reduces glare and increases contrast by roughly +1.3 stops, so it performs reliably in both photo and video workflows.

Key Features

• Circular polarizer: Removes reflections from non-metallic surfaces such as water and glass so images gain clarity and improved subject separation.
• Multicoated glass: Reduces flare and ghosting for cleaner highlights when shooting toward bright light or in complex lighting.
• Heat treated glass: Adds scratch and temperature resistance for dependable use in demanding outdoor conditions.
• Slim design: Minimizes vignetting on wide-angle setups, keeping corners free of darkening on small lenses.
• Rugged metal filter ring: The black finish metal ring gives secure handling and longevity for frequent mounting and removal.
• Multithreaded construction: Allows mounting additional lenses or filters on top, useful for stacking without extra adapters.

Who It's For

The C-PL 43mm is best suited to owners of compact and mirrorless cameras, particularly users of the Panasonic LUMIX DMC-LX100 or other lenses that accept 43mm filters who want to reduce reflections and boost color saturation. Its thin profile makes it a practical choice for wide-angle work where vignetting would otherwise be an issue.

Serious landscape and travel shooters who need a rugged, multicoated polarizer for both stills and video will appreciate the durable metal ring and heat treated glass. Those needing very high filter factors, specialty glass, or larger diameter coverage should look at other sizes or professional-grade options.

Pros & Cons

Pros

• Compact, slim profile reduces vignetting on small wide-angle lenses.
• Multicoated, heat treated glass improves contrast and resists glare in mixed lighting.
• Rugged metal ring and multithreaded design make stacking and frequent use easy.

Cons

• Filter factor varies with rotation and sun orientation, so exposure adjustments are sometimes necessary.
• Limited to 43mm lenses; users with multiple lens sizes will need additional step rings or filters.
