[0.24 lb] thank you it's the same

[Aluminum] Took my photos with my 28-70 to the next level, it now lives on that lens and probably will forever. The 1/4 grade is absolutely perfect for everyday use. Will definitely be looking into different sizes for other lenses.

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

[0.24 lb] Great purchase

[0.24 lb] This magnetic series of filters is really great. The magnetism is strong. It will definitely stay put all day. The lens cap is the cherry on top. I have yet to try other cpl filters to compare the actual function of the filter, but so far it works great. It comes in an individual case to store.

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

[Aluminum] 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.

[0.24 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.

[Aluminum] This lightweight metal framed filter is well made and functions well. There are other brands of similar filters that cost much more. I have made trial shots with it and I can say that it is a good value and great price.

[Glass] I am a film photographer and I bought this for my Pentax f/1.4 50mm lens to shoot long exposures of waterfalls. For such a low price I was prepared for problems but all of my images were beautiful and consistent, no difference in picture quality at different exposure times and different lighting conditions. The fact it is waterproof was greatly appreciated since the spray radius off some of the falls was quite impressive. Overall very pleased especially for the price, I would def buy from this brand again.
Good to note: I primarily shoot black and white, and the only color shots I took with this filter were at night, so I can't really speak to how it might affect colors. What I did shoot looked accurate and I don't see any discoloration.
