K&F CONCEPT 49mm Circular Polarizer Filter Ultra-Slim 18 Multi-Coated Optical Glass Circular Polarizing Filter for Camera Lenses with Cleaning Cloth (K Series)

Great CPL works exactly as I’ve needed it to. No issues with it and image quality is still great! No issues with color and protects my lens as well. I’d buy again in a different size.

This filter is of great quality and works great as expected. Great glass, fits perfectly . I will be buying more for other lenses.

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.

Does the job, but gets stuck on the lens way too easily.

A well made Filter, as with all the K&F products, Works just like any Big Brand filters, color is good . I've enjoyed my purchase.

Works great and haven’t had any issues!

I purchased this for my iPhone. To use with a phone cage set ups this product works really well. Cuts down the reflections on surfaces and makes my photos look way better!

Very simple to use, feels firm and works great
