This filter works for me perfectly and I am very satisfied with the results I have had while using it. It is noteworthy that the size of lens cap you need once this is on your lens will increase. I bought the 49mm and needed to increase my lens cap size to a 52mm to accommodate the larger thread size on the front. This wasnt a huge deal though as I already had a 52mm lens cap laying around. There is a size corresponding chart on the company website that will tell you what size lens cap you need depending on which size filter you buy. Hope this helps

Here in Arizona we have 320 sunny days a year. The sun is bright and intense. A ND filter is pretty much a must if you want control over the quality of the video you are shooting. This particular variable ND filter works well on my Fuji X-T4. It allows me to set my lens at f4 and keep the exposure perfect. Setting the lens at f4 means it will be in the sharpness sweet zone, thereby producing great video. It is a great ND filter for the money spent.

I ordered this lens because my regular supplier was out of the 67mm size. I am very happy with this filter. It functions the same as my other filter, appears to be very well made, and I haven't noticed any aberration in the final result. I am using this on a Canon 100mm macro.

I almost gave up on trying to invest in an ND filter because I wasn't ready to spend $200 or more on some waterfall shots. Came across this one and LOVED it. Took it on my trip to Italy, and it provided some phenomenal shots in full daylight. It worked great with both 30-second exposures of waterfalls and also when I just needed it to block out the haze from the rising sun at the top of St. Peter's Basilica. Sure, there might be a shadow around the edges, but the overall quality of the photos that this provides is well worth it.

Although I love the slim design I really do not like that my lens cap does not always fit this variable ND filter. If it did I would never take this off my lenses

What a treat to spend so little and get so much. Not only does this filter perform exceptionally good, the machining and packaging are first class. Worth 3x the price. Coincidently, I purchased a Tiffen filter in the same order. Their filter was sliding around in it's case and required carefully cleaning before I could use it. Not so with the K&F. Pristine and ready to use out of the box. Well done, K&F.

I didn't have the opportunity to try my new filter until last Saturday. Not only was I pleased when using it with my Nikon D5200 and 62mm Sigma Lens, but I hand-held it in front of the lens on my Sony HX90V while recording a sunset over the Oquirrah Mountains. Wow! The filter worked well on both cameras! No distortion at all. Luv It!

Fire the price it's a good product (I would not use it for the sky since there is vignetting but for water effects it's perfect).

I received this filter in good order and in good time. Quality seems good. This was my first experience with a neutral density filter which I used during the solar eclipse on August 21, 2017. I primarily used it as extra protection as I also used an inexpensive solar filter. I look forward to experimenting with it as it provides a variation of light. To do anything with direct sun light takes a stronger ND filter than this one. It did work well during totality (2 min. 36 sec) although we had clouds so the variable filter without the solar filter allowed me to experiment a bit. However, I tried to give limited time to this so as to experience the grander effects of totality.

Really good! Now I can take photos of everything again. The landscape, animals or secretly the neighbors. And it doesn't matter what kind of sunshine it is!
