1. If you run it on your camera, your small flashes will be very powerful. 2. I used it for a 30 second exposure at max ND and found the x was in the picture. maximum darkness. 3. I will buy everything else from them. The quality of this tool for me as a professional photographer is perfect. It even comes with a circular case to store in your pocket when you don't need it. 4. It's also great on the lens when using your DSLR for video work! It's so much easier to spin the filter around to adjust exposure instead of fiddling with your F stop or shutter speed. Bottom Line..this thing is useful and what a bargain. I I've used very expensive neutral density filters in the past and it's better than these. The 30 second noon poses are so much fun...buy it and go play! It's very fun to use.

I just got back into photography mode. So new DSLR camera setup. Never used ND filters before. I wanted to try them. This filter does what it is supposed to do. Being new to ND filters, I didn't know what to expect. It's a nice build quality, I didn't quite get the effect I was looking for but that wasn't the filters fault. This is a 2f to 5f stop filter. So I bought another K&F filter which is not an ND fader filter but a 10f stop filter. the second photo is with just the 10 stop filter. once my adapter arrives (the filters are different sizes, 52MM and 55MM) I could even stack the two together, up to 15f slower. Generally,

I received this variable ND as a birthday present to equip my Lumix FZ300. I used it last night and it worked great. Excellent for bright days, slowing water, and sunset shooting.

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.

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.

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.
