[Aluminum] I got fed up with threaded filters jammed together, such as when combining a CPL with an ND. Magnetic filters also save me precious time when preparing a shot in rapidly changing light.


I looked into all the magnetic systems available and chose K&F on the basis of selection and cost. Optical quality is right up there with threaded filters for which I'd paid much more. I am using K&F magnetic in 49, 52, 67, 77 and 82 mm sizes.


K&F has two magnetic adapter base rings. This model is an open ring. The other selection is a base ring fitted with a protective U.V. filter (rear side threaded, front magnetic flange). When in adverse conditions I switch to that, but for most use I have only these open rings on my lens, adding my CPL and NDs as desired.

[Multi Coated] The K&F Concept Nano-X Filters are well made. I've purchased two 67 mm and one 77 mm and all three fit my lenses perfectly. Optically they have no practical effect on image resolution or light transmission and produce no added glare. These are well-made, reasonably priced filters with exceptional optical performance. It's amazing how much multi-coating technology has improved in the last decade and K & F seems to be fully competitive with the best filters available anywhere.

[5 x 4.4 x 0.7"] I didn't notice any light leaks, color cast, vignetting or an x-effect.


These K&F filters have a hard stop at both ends whereas some of their other variable ND filters spin freely.


Overall a really great value. Perfect for video!

[Glass] I bought this for my Sony 20mm 1.8 which has a 67mm filter thread. The lens is so wide I would get a lot of vignetting in the corners. This completely solved it, the magnetic hold is strong, the filter quality is great and all of my issues are solved!

[Glass] 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.

[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.

[Glass] thank you it's the same

[Multi Coated] Bought specifically to use with my GF lenses for the Fuji GFX 50r. Truly does give a more filmic look right to the RAW files. Great for back light and creating natural lens flare. Skin texture is lovely as well.

[5 x 4.4 x 0.7"] If you're looking to try long exposure on a budget, this is a very solid buy.

I bought this for a first attempt at long exposure waterfalls and I am immensely pleased, especially with the price point. I shoot black & white so I can't comment on any possible color aberrations, but all of my shots are clean and sharp. It took getting sprayed by waterfalls in the middle of winter very well, cleans easily and threads smoothly. Best paired with 100 speed film on bright sunny days, it only took me down to 1-2 seconds with 400 speed.

[Aluminum] 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.
