1. When you run it on your camera, your little flashes will be very powerful.
2. I used it for a 30 second exposure at max ND and found that the x was in the frame. maximum darkness.
3. I buy everything else from K&F. The quality of this tool is perfect for me as a professional photographer. It even comes with a circular case that you can slip in your bag when you don't need it.
4. It's also great for the lens when using your DSLR for video work!

I have a Sony A7III with some of the Tamron lenses they recently released, 67mm thread on the dUKx. I first used the ND on a daylight midday shoot and was amazed by the results. The best part is that I can choose the number of stops I need to make the zebras disappear with ease. Ease of movement and robust construction. Only negative is that the sun visors don't fit after turning on the ND. Not a deal breaker but be aware.

EDIT: I also took it on a trip to Lake Tahoe and it came in really handy for longer exposures and more sky contrast. Awesome and so easy to use!

Perfect for my needs.
I shoot a lot of outdoor videos and since I can't change my shutter speed, photos tend to be overexposed if I leave my aperture wide open.
I have used this Nd filter from minimum to maximum and the image is still clear and sharp.
Fits perfectly with my Sony 24-70g Master

An ND filter that keeps what it promises. As soon as you unpack it, you notice that great value was placed on high quality. The transport cover is already very neatly worked and thus ensures safe transport of the filter. The filter itself is really well made. As soon as you unscrew it, you can tell that everything feels really good. The metal ring is a bit frosted, which ensures a great grip, especially when adjusting. Adjusting between ND 2-32 works seamlessly and is really smooth. Absolutely jerk-free but also heavy enough that nothing changes so quickly.When adjusting it yourself, you don't notice any disturbing influences such as the typical cross, which was often the case with variable ND filters.The value from ND 2 to ND 32 is also perfect for the most long exposures. This ND filter is perfect when it comes to sunsets or the typical smoothing of water. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place. What was important to me was that the filter is not so thick and heavy. This is where the K&F Concept ND Filter really shines. It is almost as thin and narrow as a normal UV filter. A feature that I like very much. Since the filter starts at ND-2, you wouldn't have to write it off even with normal photos and can vary very quickly. After my first tests, I have to say I wouldn't want to be without this filter in my camera bag anymore. In addition, the filter is nano-coated so that water droplets roll off directly and the filter cannot fog up in the first place.

This is my first square filter! The first thing that struck me was the very elegant and practical packaging - the ring that takes the filter out of the storage box is very clever.

Far exceeds expectations. Quality of packaging matches a much more expensive purchase. The visual quality of the filter is equally top-notch. After using the filter in my filter holder, I can't see any evidence of color cast or filter clarity. Overall, I have nothing but great things to say about this offering. Will definitely look to this manufacturer for future filter purchases.

I am very satisfied with the optical quality of this filter. Especially in comparison (eg with Cokin) it proves that you don't work with a plastic toy. The transitions are smooth and not immediately (frighteningly) noticeable

This is already my 2nd gradient filter from K&F, I still have the GND 0.8 and am very satisfied. Simply unbeatable for this price. I can't see any color distortion.

When comparing dUKx footage sets with and without, be aware of quality differences.

I find this filter ideal for photo and video.
But at 10mm on my 80D Crop captUKr it casts a shadow over it.
When I zoom a pUK like 14mm it disappears.

NO X, no coulUKr dominant. Excellent filter... As advertised. and nice build...
