I bought the gradient filter because it was recommended to me by friends.

Description: The rim of the filter is made of matte black coated aluminum, I assume. The rim itself is actually quite nice. The wide, ridged design around the base of the filter makes it easy to put on and take off. The high index optical glass is in fact nano-coated to protect against water/oils from fingerprints, rain, etc. The glass itself has a slight yellow cast (which you can see in the photo comparison), but this can also be easily corrected using the automatic white balance of your camera or Lightroom.

bought this adjustable ND filter to use with my Canon EF lenses on my trip. It worked like a charm and allowed me to capture some beautiful scenery!

Very good quality filters, very good rendering

Bought this for a recent trip to Rome. Never came off the lens. terrific build quality and performance. worked silky smooth, love it!

I just got back into photo mode. So the new DSLR setup. I've never used an ND filter before. I'd like to try that. This filter does what it is supposed to do. As a newbie to ND filters, I think this is a good build quality.

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-term exposures. This ND filter is perfect when it comes to sunsets or the typical straightening 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. Which is still 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.

Top product!

At the time of this review, I've had the filter for about 4 days. My favorite attribute about this filter is the lack of "X" issues in photos. With many filters of different nUKter density, you can rotate the filter too far and create an accidental "X". K&F solved this problem by allowing the filter to only be twisted at a specific point so using it doesn't accidentally ruin the photos. The filter is very robust and robust. The non-rotating part of the filter has grooves to easily hold and rotate the outer ring. Great product so far.

The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in both the direction of ND32 and ND2, making the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at minimum (>ND2), only turned a little further did I actually have ND2. So it went from slightly darkened (>ND2) to bright (ND2) to significantly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.
