K&F CONCEPT 52mm Circular Polarizer Filter Ultra-Slim 18 Multi-Coated Optical Glass Circular Polarizing Filter for Camera Lenses with Cleaning Cloth (K Series)

It's great. Really improves color (just be patient and rotate the filter carefully), gives much better (optical) result than image processors. You'd lose 1-1.5 F but worth it. Could even be very useful in darker environment where sporadic light sources are present. Not exactly cheap but good investment in thousand of photos. Shipping was fast. Thanks.

As far as I can tell, this filter rocks for my use-case. I wanted a weaker filter for low light. I have not used one for many years, however. Nothing to compare it to.

Looks snazzy! Oh, you want more? Well, I'm new to more than point-and-shoot photography, so I'm far from an expert. But it seems to be put together well and functions as expected. You twist it and can cut glare or get some deeper blues. What's not to like? I mean, sunglasses for my camera? Definitely!

I picked up the K&F CONCEPT 52mm Circular Polarizer to help manage reflections and pop the blues in my landscape shots. For the price, the glass quality is genuinely impressive. I didn’t notice any weird color casts, which is usually my biggest fear with more affordable filters. The multi-coating does a solid job of keeping flare down, and the polarization effect is smooth and effective. However, the ultra-slim design is a bit of a double-edged sword. While it’s fantastic for preventing vignetting (even on my wider lenses), it can be a little tricky to grip and rotate if you have larger fingers or are wearing gloves. Overall, it’s a high-quality piece of glass that performs way above its weight class. Just be prepared to be a little patient when adjusting it!

Works great though not as good as the more expensive filters but the again it's just a filter. Spend your money on a good lens.

Perfect for the style I look for when it comes to my photography. Photo quality is still top-quality despite the filter having a noticeable surface on the glass for the effect it gives. Fits perfect on my sigma 16mm, performs exactly how I expected! I also plan to buy a 1/2 filter because while this filter is perfect for most, I still find myself needing a bit more.

Really nice quality for a great price. I've used several with excellent results.

As described

Disappointed. Not as described. It just mskes a shade on picture.

Good, it removes reflections very well and doesn't soften the image quality, just dont do my mistake and getting it thinking it removes lens flare too. This CPL filter only removes reflections not lens flare👍 . U can remove lens flare by using a lens hood or slightly changing ur angle or position. but this filter? It Wont remove it, nor any filter in the existence could do that

Très bon rapport qualité prix

+ Bra budgetkvalitet! + Bra polarisering! -Sätter sig fast lite i gängan men man behöver ju inte dra åt det med skiftnyckel när man ska ha på det. Jättebra produkt🙂👍

I’m genuinely impressed with this CPL filter. The build quality is excellent — slim, lightweight, and easy to mount. It dramatically reduces glare and reflections, especially when shooting water or glass surfaces, and enhances color saturation beautifully. The multi-coated Japan optics deliver sharp, vibrant results without any noticeable distortion. A must-have for any serious photographer or videographer. Highly recommended!
