Worth spending the extra money. I've combined this with step up mounts to use this one filter across several lenses.

I'm not professional, but I had more fun with the photos.

I have a Sony A7III with a couple of the Tamron lenses they recently released, 67mm thread on both. I used the ND for the first time on a mid-day daylight shoot and loved the results. The best part is being able to dial in the number of stops I need to make the zebras disappear very easily. Smooth running and sturdy construction. The only negative point is that the sun visors no longer fit once the ND is switched on. Not a deal-breaker but be aware. EDIT: I also took it for a trip to Lake Tahoe and it came in really handy for those longer exposures and getting more sky contrast. Brilliant and so easy to use!

Delivery - Fast, punctual and safe packaging. The filter has its own box, in which you can safely go out into nature to take pictures. Have you ever tried photographing water in direct sunlight? Passing the waterfall and you want to take an amazing photo, but due to too much brightness your options are limited - believe this has happened to me many times, but with the K&F Concept ND filter the problem is solved. I'm an amateur photographer who loves spending time in nature and I think ND Filter is something you need to have in your gear as soon as possible. The ability to set how much you want to close the filter and thus get a darker filter is a great thing. The filter is mounted directly on the lens, just reject it (note the size of the lens!). You can still take it, it's not difficult and you get great effects with it! Long exposures without ND filters are a nightmare, and having ND filters in your pocket will be an amazing thing. Another thing I would recommend is the mobile app (there's more - just try) to calculate shutter speed using the ND filter. You can find the formula on the internet, but we have to use the technology correctly. I highly recommend K&F Concept filters! and having ND filters in your pocket will be an amazing thing.

Excellent value for money, does not affect image quality in any way, thoroughly tested produces no vignetting or flare or ghosting. Mounted on a 24-70 and a 70-200 really essential for creative shots but especially valid on the video side. It allows you to work on open apertures on sunny days while keeping 1/50 S as the shutter. Feeling of absolute solidity! All-metal structure and solid and precise ferrule in the transition from one ND to another! perfect filter

It's a great option for outdoor shooting, whether photo or video. You can easily twist the filter to change the amount of light entering the lens and it's much easier than having to constantly change filters of different strength or using a 4x4" filter like a Cokin filter. there is no vignetting or "X" pattern that can show up in other models. It's very easy to use, even for the beginner and it's a good thing to have when you want to travel lighter and plan to shoot outdoors.

The marking on the side of ND2 - ND32 is fixed so that you cannot exceed them and accidentally get a cross on your video. Notice no difference in quality when comparing two footage sets with and without. Keeping one of these in your camera bag is a must if you're shooting video and will also help if you're into photography and want to do long exposures.

I am always wary buying optical products that I will lose some image integrity. I used this with Canon L Series lens and results were tack sharp.

Some of the best filters I've used! I was sent these filters to test and review, but I will never review a product on which I cannot give an unbiased and honest opinion. I have personally tried this filter and found it to be of very good quality and on par with some of the more expensive brands. I would buy this!

I shoot with the Fujifillm X-T3 which is arguably the best video camera under $3000. However, it lacked the variable ND filters you'd find built into a more professional video camera. I needed more motion blur and lower my exposure when shooting video and this amazingly does it without any noticeable loss of detail and color. For the price, it's a very valuable tool in my arsenal. The build quality is really nice with an all metal construction. The ring itself is smooth and allows for good variable exposure change. I really like this ND filter and think everyone should give it a look as the image it produces is pretty clean.
