mounted this on the end of my Canon lens. It screwed on flawlessly. The threads are well machined. What I like most about this is the convenience of not having to carry several filters. I am not a professional, but I like to take a lot of pictures. The adjustment rings turns easily and it moves infinitely without notched stops. In my use, I found no issues with my pictures. I did not experience any vignetting. This gives me the ability to practice my shots while simply rotating the ring and not having to change out filters. It works well for a relative novice like me, until I gain more experience with this type of filter. I noted that once mounted, you are unable to use your existing size lens cap. Not a big issue, however.

The K&F Concept Variable ND2-2000 filter is a brilliant and much needed photo accessory if you work a lot with flash or in hard sunlight setups. I had not in the past used ND filters much. But in recent years I have been shooting more and more with fill flash in hard sun lit conditions. As most photographers know, once you sync a flash with your camera the top shutter speed is capped, usually at 1/125 sec. Sometimes even the smallest aperture on a lens isn't small enough to cut the light level down enough. And of course you don't really want the smallest aperture as lens performance usually starts to suffer at smaller apertures. That pretty much guarantees over exposure problems unless you can cut down the light input. In the past you had to carry a variety of ND filters for various stops. But this new variable ND from K&F has a 1-11 stops range. Just amazing. It's like having a second aperture ring. You can just dial down the light volume until the other exposure parameters you care about, histogram, zebra, etc, all align to your liking. Absolutely a great buy if you need what this filter has to offer.

& F Concept markets innovative, high-quality products. This filter is no exception. If you appreciate fine machining, you’ll love the appearance and feel of this filter. It’s a precision device. To adjust the filter over its 11 stop range (ND2 – ND2000), you simply twist the outer ring of the filter. There are 10 gradation marks on the ring. I haven’t been able to test the extremes of this filter’s range: I need a couple of really sunny days to do that, I live near Lake Michigan and I’m going to try to get to the shore on a day with moderate or more wave action and test my wife’s patience as I test the impact of this filter. Just looking through it and rotating the ring through its range, I get a pretty good idea of what it can do. The filter come packaged in a protective plastic case and is supplied with three vacuum-packed cleaning cloths. I haven’t opened any of those pouches yet. Definitely a keeper that has me yearning for some sunny days before winter ets in.

As with all of the company's accessories for photographers, this is an absolute recommendation for a smaller budget. Of course, not everything is perfect, but you shouldn't forget the quality you get for this relatively low price! It's especially great for beginners to try out.

The results with this filter are excellent. I just had a small problem because the original cover no longer went with the filter. After contacting the company, the reaction was perfect. They sent a new cover with goodies in addition, the contact was cordial and professional. Bravo, I recommend 100%.

I have this handle filter by K&F and it cannot contain negatives. I often use it in the city to make people disappear with a long exposure.
