It's a must-have item in your camera bag and for a fraction of the cost of other brands of variable ND filters. So far I've tested it with multiple lenses and 3 different cameras using step down rings in low light and full daylight, low ND2 down to DN32 and so far I haven't seen no X pattern. A huge problem with many variable ND filters, even the most expensive ones. Color cast is also insignificant but like ALL inferior ND filters there will be color cast, hell even a $500 will have some sort of color cast, again at a fraction of the cost to have a barely noticeable color cast, or at least one that cannot be easily corrected in LR Nowadays, I shoot with the Sony mirrorless system and every lens I shoot with on my full frame camera has a thread less than 77mm and vignetting is no longer an issue at any filter range and at any what focal length of the lens and i have been shooting the thing a LOT with my sony. Above are some of the photos I took with the filter, including my Canon 5D series and my Sony A7R series. The first 3 are from my Canon and the second 3 are my Sony lens and I've been shooting the thing A LOT with my Sony.

I was surprised how accurate the stop markings are. Well built. The rotation is a little stiffer than I would like but is definitely usable. Best filter at this price point but I would think it would be at a slightly lower price. The 49mm filter takes a 52mm lens cap.

I ordered this filter and wasn't sure what to expect as it was cheaper than most brand on the market, I have to say I was very pleasantly surprised!The filter is very solid with a full metal construction. The outer ring spins smoothly and feels solid when adjusting on camera. The images remain very sharp and I'm impressed there was no vignetting like some other ND filters create. I also really appreciated the hard carrying case that it was delivered in as I can carry it with me on shoots without fear of it being damaged.I would definitely recommend to anyone needing a variable ND!

I was skeptical to buy any filters since I have very expensive glass but this is very impressive!! For the nerds out there, at sunset I can shoot at 1/160 and get the colorful clouds no problem

I am so glad I bought this filter. I have a Sony a6300 that I have owned for about three years. I never dropped it until I got my K&F filter. Since then, I have dropped it on hard concrete and thank God I had my K&F filter on it. I have a $400 Sigma lens and it protected it. There are only tiny dings in the filter. BTW - the ND is fantastic. I really love the quality and strength of this filter. Fantastic filter and well worth buying many more in the future for me.

This thing is excellent - I can't detect any issues with it at all. It's clearly marked for ND2 - ND32 so you can even set up your shots with math instead of looking at the viewfinder!

I recently got into photography and always wanted to take exposure shots, but couldn't do it without this filter after doing some research online. It screws onto the lens protector and I can even mount my lens cap on it. Like the fact that it adapts to any type of photos I want to take depending on the time of day and the position of the sun. I took a 2 second exposure shot of Niagara Falls and it turned out fine. I also added a still photo for comparison. I will do more exhibition photography, I am improving every day after trial and error, I must buy if you like exhibition photography, you will not regret this purchase.

I haven't noticed any vignetting or X's in my images or videos. Seems like really good quality and love the flexibility of having multiple ND stops in one lens filter. Glad I bought it.

I have only ever used this variable ND. I have no experience with a more expensive or higher quality ND filter. WITH THAT SAID... I have nothing but good things to say about this ND. As a full-time videographer, I love using this ND when I'm shooting outside. makes getting a good exposure very easy. there is a clear vignetting when it is very bright outside. i recommend this overall.

I use the anamorphic lens by Moment and FilmicPro to make movies using my iPhone. The 62mm K&F filter is very important to get that filmic look when I am shooting at 24fps. I have tried cheaper ND filters but they had vignetting and poor image quality. With the K&F filter the clarity is great and the build quality is solid and durable. The included case firmly holds the filter. This ND filter is a great value and much better than the other lesser ND filters I have tried. I have included photos with the same camera settings without any filter, with a cheap filter and with the K&F filter. I also included a photo of the setup I use. This filter pairs perfectly with the moment 62mm filter mount. It is a game changer for anamorphic video especially when filming outside. I could not be happier with the K&F ND filter. It is superb quality and value! I totally recommend it!
