Fast delivery. Good value for money. With a little practice, you can achieve good results. A must-have in your camera bag.

Very good polarizing filter, nothing like the cheaper filters you can find here and there.
You can feel the quality at your fingertips; the results are perfect, the colors are consistent, and there's no visible distortion. So, less post-processing is appreciated.
This brand has never disappointed me; its products perform well and are always reasonably priced considering the quality.

The polarizing filter impresses with its excellent workmanship and quality. It attaches easily to the lens and sits securely without wobbling.

The photo results are impressive, with clear colors and strong contrasts, without any distracting color cast. A reliable polarizing filter that enhances the photography experience.

The filter promises to be a 2-in-1 polarizing filter that can remove reflections and enhance contrast, while also being a "true color" filter that eliminates color cast. The coating also claims to be particularly low-reflection and resistant to scratches and contamination.
In fact, in practical use of the 77mm filter with my RF 14-35mm F4L IS USM, this seems very consistent to me. When activating the polarizing filter effect, the image is slightly darkened, and as expected, bright or reflective areas in the image disappear in certain shooting situations (depending on the incidence of light), but I can't detect any additional color cast, for example. The filter's dirt-repellent properties make it easy to clean.
In my opinion, the filter is a good choice, especially for landscape photography, and meets my needs for a polarizing filter.

The K&F Concept 2-in-1 True Color Polarizing Filter in 67 mm impresses with outstanding color accuracy, minimal reflection, and first-class workmanship. Thanks to the state-of-the-art Nano-Xcel coating, this filter offers unsurpassed image quality that will delight both professional photographers and ambitious amateur photographers.

Precise Color Reproduction Without Yellowing

At the same time, it filters 99.9% of polarized light with a light transmission of 45%, ensuring maximum contrast and the finest details remain visible even in difficult lighting conditions.

Premium optical glass for razor-sharp images

The filter features premium lenses made of Japanese optical glass, polished on both sides. This masterful craftsmanship guarantees brilliant sharpness without image noise, even in strong backlight or unfavorable lighting conditions.

Robust Nano-X coating – water, oil, and scratch resistant

With a 28-layer nano-coating, this filter is extremely resistant to water, oil, dust, and scratches. This keeps the surface clean and easy to clean – perfect for use in harsh environments and changing weather conditions.
