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.

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

The quality is convincing. No blurring or color changes. There is a case for it. Value for money totally convinces me. Clear purchase recommendation.

Perfect, the adjustment is very progressive and practical, no chromatic aberration, sharpness is preserved. In short, nothing to say, it's an essential and very versatile tool, accessible to everyone. I recommend.

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

Very well made... I have bought Hitech filters before but when I compare the quality of Hitech to K&F I have to say that K&F is far superior. Item was dispatched next day and arrived very quickly. No complaints

I've been using the product for about half a year (almost daily) and I'm very happy with it! Pro: Installation is easy and holds up very well, and with the installation rings it can also be used universally for any lens! The filter also holds its Promise and the quality is still excellent!

I'm not a pro but I had more fun with the photos.

great product. better than Lee Filter in every way. made of glass makes them more durable than the scratch-prone Lee filters

was sceptical about this product with the price but this is a great ND. I haven’t done any ‘proper’ testing but from the footage I’ve shot with it, it’s 10/10. No noticeable colour cast or any vignette. I would recommend!
