Good product, good seller and fast shipping. I would recommend this product to anyone who wants a good bang for their buck ND filter

have an ND 400 that I use for waterfalls etc but I don't always want to block that much light so I looked for something a bit faster maybe an ND16. I've had variable filters in the past but have never been happy with the dreaded Xs the screen when you rotate it or an uneven color cast across the screen. I saw the K&F ad that said you didn't have any of these issues so thought I'd give it a try and they are great, very even light reduction across the frame and no Xs.I have the 77mm filter he is really well made, there are stops on rotation so it's easy to see where the limits are, the frame itself is slightly larger than the 77mm so no chance of vignetting in the corners, the small downside to this is I can doesn't seem to attach the filter with my hood, but that's no big deal. We recommend.

I absolutely love this 77mm filter and it fits my Nikon 70-200 f2.8 perfectly. I use reinforcement rings for other lenses like my 85mm f1.4. The ease of use is phenomenal and it glides so effortlessly. I love this filter. I can recommend him to everyone. Push it to the darkest level, open the aperture wide and take a long exposure during the day for amazing results. Enjoy!

Works great if you're starting out with long exposure photography, but has a bit of vignetting and color cast

I used it on my 17-55 Canon 2.8 lens for video. It is wonderful! Nice feeling to turn it, perfect case for transport included. Does j not have an "x" when used at 8 stops! Does not affect the picture quality. I have a similar, only more expensive, other brand that doesn't work as well as this one. I am a professional cameraman and I trust this brand!

ND filters are expensive, everyone who has dealt with them was. Here you get a top product for good money.

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

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.

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.

The filter comes in a very elegant packaging with a magnetic closure and also has a small plastic box for transport. The filter can be easily screwed on and off the lens , estimated at the maximum setting 3-4 full f-stops. You can see the effect best in backlight or strong contrasts in the subject, I'm looking forward to testing the filter in the midday sun in summer.
