Really high-quality UV filter
I ordered the K&F Concept Nano-X PRO series UV filter to use with the Pentax HD DA★ 11-18mm F2.8 ED DC AW lens. I usually use my high-quality lenses without a UV filter. Ultimately, any additional glass in the optical path degrades the quality. But in dusty weather or when it's raining, using a UV filter is definitely a good idea, as you can then rub the filter dry with a cloth or remove dust. If the filter gets scratched, the front lens of the lens is still undamaged.
Now for the filter. The K&F Concept Nano-X PRO series UV filter comes in quite elaborate packaging. The filter is in a pouch, parts of which are even made of real leather. The closure is magnetic. There is a strap on the side of the pouch. If you pull this, the filter slides out of the pouch.
A cleaning cloth is also included in the delivery, and a cardboard stand (?). I don't really understand the point of this. Perhaps it is intended for presentation purposes for dealers?
The filter is "Made in China". There is an importer's address from Germany on the box.
The filter can be easily screwed onto my Pentax HD DA★ 11-18mm F2.8 ED DC AW lens. There is nothing to complain about. The Pentax HD DA★ 11-18mm F2.8 ED DC AW lens is not shaded by the filter. The filter's workmanship is also really good.
I took a few test pictures with and without the filter, and could not see any negative effects. Under normal conditions, I don't think the image result will really deteriorate. Perhaps there are problems with light reflections in backlit pictures when the sun is at the right angle. But that would be a general problem with filters on lenses.
Conclusion:
The filter is really good. The current price of €149 for the 82mm filter is certainly anything but a bargain. Ultimately, it doesn't make sense to buy a lens for around €1500 and then screw a cheap filter onto the lens, which then leads to poorer image quality. I give the filter 5 stars.
