[0.18 lb] Excellent build quality, filter turns super smooth and works great. Such a nice feature having 2 in 1.

[0.18 lb] I purchased a Nikon 500mm f5.6 and this filter to protect it. This filter does not interfere with the lens hood and the lens cap snaps into it fine. I liked the high light transmissiveness for the price.

[82 mm] That K&F Concept filter is really excellent stuff, in the range with famous Hoya filters for amateurs. Filter for 21. century photo-, film- and video-enthusiasts!

[0.18 lb] Super simple & light durable with the leather tab

[82 mm] Well made, does exactly what an ND filter should.

[82 mm] Works great with Leica D-Lux 8

[0.18 lb] Used in Seattle, great for neon signs.

[0.18 lb] I recently purchased the K&F Concept 1/4 Black Mist Filter from B&H, and it has quickly become one of my favorite photography accessories. This filter adds a touch of enchantment to my shots, softening highlights and infusing them with a subtle misty quality. It strikes the perfect balance at 1/4 strength, preserving critical details while creating a dreamy atmosphere. B&H's seamless shopping experience and prompt delivery made the purchase a breeze. I'm thoroughly impressed with both the product and B&H's exceptional service. The K&F 1/4 Black Mist Filter has unlocked a new dimension of creativity in my photography, and I couldn't be happier with my purchase.

[82 mm] A filter like this is a MUST HAVE if you want to level up how your images (for photography and video) look in broad, intense daylight in one fell swoop.

They reduce the overall amount of light coming in the camera so you can stop down for a beautiful optically blurred out background and heavily reduce intense sunlight reflections, virtually adding dynamic range in daylight. I knew this would help my shots but my jaw dropped when a got the footage back from testing locations for a project, with and without. (attached photos are screen grabs of video. Shot on Sony A74, Sigma 24-70 f2.8) *Note: This is my first ND filter and first polarizer.

My testing has found a slight cyan cast in the area where sunlight can hit the lens where shadows can be seen, it looks almost dreamy and I kind of like it, but not perfectly color preserving. With Nano-X Pro, I have not encountered any dark X pattern no mater how I adjusted it, which is far better than most Variable ND + Circular Polarizer filters on the market. The included pouch is made of materials that feel great in the hand and its pull tab that makes the filter rise out of the pouch is a very nice touch that makes me wish K&F Concept included this pouch with more filters and also sold separately. I want other filters in these things! (Wile they do sell other pouches. They do not sell the ones included with these filters.)

If you are on the fence and don't have a ND or polarizer, just get it. It took a while for Polar Pro to finally release something like this, and the price of this one STILL undercuts it. If you are a videographer/photographer, image quality is super important and this is a fantastic tool to help you properly expose your shots. There is a reason why Directors of Photography have built in ND filters on their wish list for their cinema cameras and this is why, it makes their job so much easier and allows them to focus on building the look that they want.

[82 mm] I was very surprised at the results of this filter. I wasn't expecting much based on it's price (sale price especially), but when I tested it, I noticed virtually zero difference in sharpness. I also didn't notice much of a color shift either when using it. Definitely worth the money!
