The "K&F Concept Nano-X PRO Series ND1000 Filter 77mm Gray Filter (10 Stop) Flagship ND Filter Slim Neutral Gray Filter" is delivered in its original packaging. ✅ The processing is very high quality and has a sustainable idea + implementation. The interior can be used as a picture frame, which I find very successful. ✅ The filter is delivered packed in a very sturdy leather case. A wrist strap is sewn in, so you could wear it on your wrist if you wanted to. A microfiber cloth is also included. ✅✅ The filter itself is really high quality and feels the same. A stable and good metal frame with a decent feel / surrounding structure. ✅✅ The gray filter darkens the image by 10 f-stops, which is really a hell of a lot. But this way you can "stop down" properly even with a lot of light and shorter exposure times and of course also take corresponding long-term exposures. I didn't notice any aberrations or an uneven gradient. Really great! ⚪ The only thing I would have wished for is a sturdy box in the carrying case. As good and attractive as the bag is made, the filter is not protected against dust and external forces, which I would have wished for in this price range. All in all, a really high-quality filter for a corresponding price of just under 200EUR. Whether you want to and have to spend that much is an open question. I'm missing a small box and the price could also be a bit lower, which is why I give it a solid and recommendable 4 stars overall if you have the appropriate budget in the petty cash box. —
