In the past, I've taken nature photos in bright sunlight, especially with fairly cheap filters. This often led me to enjoy nature photos in these situations, as the photos often had a color cast, blur, etc. I was
therefore undecided whether I should even try out the K&F Concept filter, but then I gave it a chance and that was a good thing!

As soon as you unpack it, you notice that you are holding an absolute high-end product in your hands. The genuine leather case, the brass-metal frame, the filter itself, make you extremely (!) high-quality impression.
Thanks to the brass frame, the filter can also be screwed onto the lenses extremely easily.

The filter reduces light by 10 stops, so it is specifically intended for nature photographers who want to take landscape photos in bright light without deserted or “sunken” areas.
It also works great, without color strokes, color fringes or other imperfections. You don't “see” from the image that a filter has been used and that's the main thing. I've never had the luck with cheaper filters in the past.

The filter is super easy to screw on and off and does not affect the autofocus on my Canon R5 either. At least not when there is enough light, of course.

I'm really impressed and can say that with this filter, K&F Concept has completely eliminated my aversion to filters of any kind. Therefore 5 stars
