A quality CPL filter
Since the filter was positioned as a member of their flagship lens filter line I definitely had already high expectations in the K&F Concept Nano-X PRO CPL filter.
It certainly made its first impression while unboxing it -- it comes in a stylish box and inside that box is an elegant leather filter carry case.
But more important is of course what it delivers in front of a lens. And that is indeed amazing: I tested it on different lenses, a 70-200 mm lens and on a 35mm. Based on physics of a CPL filter in general it is not advised to go wider than 24mm.
I found no distortion problem; reflection and glare get well mitigated; no vignetting or spots, or dark areas detected within the focal lengths mentioned. Also, of course, keeping a certain angle towards the sun will determine the outcome.
That is definitely a high-end filter and I think K&F has made it into the professional market and its expectations.
I was happy with the test results and can recommend this filter, it is a well-worth investment, and my motto is 'better no filter at all than a cheap and bad filter'.
