C-PL Circular Polarizer Multicoated 55mm - Slim Multithreaded Filter

In this review of the C-PL Circular Polarizer Multicoated 55mm, the bottom line is clear: this is a practical, affordable polarizer for Lumix FZ70 and FZ80 users who need better contrast and reduced reflections without bulk. The filter delivers noticeable color saturation and reflection control while remaining slim enough to avoid vignetting on the FZ70/FZ80, and its multithreaded design makes stacking or mounting additional filters straightforward. The review focuses on real-world handling, optical effect, and construction so photographers and videographers can decide if it fits their kit.

Key Features

• Circular polarizer: Removes unwanted reflections from non-metallic surfaces like water and glass to boost color saturation and contrast in both photos and video.
• Multicoated, heat treated glass: Improves light transmission and reduces flare for cleaner highlights and more consistent color.
• Slim design: Minimizes vignetting on wide-angle or compact bridge lenses such as Panasonic Lumix DMC-FZ70 and DC-FZ80.
• Rugged metal filter ring: Black-finish construction resists handling wear and gives a solid mounting surface that stays true when rotating the filter.
• Multithreaded mounting: Lets you attach additional lenses or screw-on filters on top without needing adapters, useful for video rigs or layered filters.
• Variable filter factor: Provides roughly +1.3 stops depending on rotation and sun orientation, letting users balance exposure and polarizing effect.

Who It's For

The C-PL is best for owners of Panasonic Lumix DMC-FZ70 and DC-FZ80 or other cameras using a 55mm filter size who want improved sky contrast, reduced reflections on water or glass, and slightly richer colors during outdoor shoots. It suits hobbyists and content creators shooting both stills and video who value a slim, durable solution that does not introduce vignetting.

Conscientious landscape photographers or professionals who demand the absolute highest color neutrality and multi-layer anti-reflective systems may prefer higher-end or brand-specific filters, but for most photographers seeking a durable, effective polarizer with multithreaded convenience, this filter is a sensible, cost-conscious choice.

Pros & Cons

Pros

• Effective at cutting reflections and increasing color saturation in outdoor scenes.
• Thin profile reduces the chance of vignetting on compact and wide-angle lenses.
• Solid metal ring and heat treated glass feel durable in regular use.
• Multithreaded design makes stacking filters or adding lens accessories easy.

Cons

• Filter factor varies with rotation and sun angle, so exposure adjustments are often needed for consistent results.
• Not marketed as a professional high-end optical brand, so perfectionists may want to test for color neutrality under critical conditions.

Frequently Asked Questions

Will this cause vignetting on wide lenses?
Because it uses a slim design, the filter is specifically intended to minimize vignetting on compact and wide-angle setups such as the FZ70/FZ80.

Can I stack other filters on top?
Yes, the multithreaded ring allows additional screw-on filters or lens accessories to be mounted on top.

Does it change color balance?
Circular polarizers of this design do not affect overall color balance, but the multicoating helps keep color neutral while improving contrast.
