I've been a fan of K&F Concept for a long time and have a lot of filters. Especially in the beginning, the cheap products were a real boon for my wallet. I simply couldn't afford expensive polarizing filters, ND filters, or adapters. However, they impressively demonstrate that K&F Concept can also be absolutely high-quality with this filter series.

I can report that just unpacking the filters is a real pleasure. Although this doesn't count directly into the review, it immediately gives off a completely different feeling than with the brand's other product series. It continues with a very attractive and haptically convincing case, which allows the filter to be removed via a tab.

But now on to the filter itself. I already have several polarizing filters in use, but none of these filters really convinced me as much as the Nano-X PRO. The workmanship is simply excellent, the weight is comfortable in the hand and the thread is fun - when screwing on and even unscrewing again. Most people will be familiar with it, cheap filters like to stay in place. The optical performance, which is ultimately important, is great. Reflections are skilfully filtered and there is also no distortion of the actual image. The look that is created is simply great. When you do some magic in post-processing, photos of cars simply look amazing, a completely different level. I can therefore make my recommendation without hesitation.
