49mm Variable Neutral Density ND8-ND2000 ND Filter for Camera Lenses with Multi-Resistant Coating, Waterproof Nano-Dazzle Series

I am very pleased with this 67mm ND filter from K & F Concept. I am using this on a Sony 24mm 1.4 G Master lens (Bonus it will also fit on my 85mm lens). This is great for time lapse photography during the bright afternoons in Florida. Examples of the scenes I've shot are, the summer rains coming through over the water, or of the city scenes at the urban farmers markets, etc., this filter has exceeded my expectations.
I purchased at medium sized backpack from K & F 2 years ago that has been a hearty addition. The backpack has protected my gear on trips to Thailand, Hong Kong, Philippines, and Colombia. So, I figured why not try their other products. I'm looking forward to using these filters for many years to come.
Great buy at a great price.

I ordered the variable ND filter and I am super happy with it. It arrived well packaged and quickly. A small box of foam is also included. The filter has levels 8 to 2000, which is ideal for filming. I have it on my Sony A7iii and it works great there. It is of course also suitable for photography, but there I would personally always use a fixed ND filter. So far I have not been able to detect any strong vignetting and the colors do not get a noticeable color cast either! Price-performance ratio is great here! You can access here without hesitation.

I tested the filter for the first time this year for three weeks in Berchtesgadener Land. For the ideal companion on the go, which neither takes up too much space in the backpack nor in the small, light bag. In terms of quality, it does not completely replace the large filter systems, but whoever is already with "hobby equipment" or, like me, is out and about with somewhat older equipment, can be more than satisfied with the quality. And: it takes up significantly less space. I think it's great that the filter can be continuously adjusted. The same applies to the scope that the filter covers. However, I would have liked numbers for the markings and not just squares. That would allow a little more planning and calculation and a little less trial and error at the beginning. But over time you know the values ​​after all.

Sharp, generates nice colors, good price!

Its great quality dynamic range all in one ND filter, perfect fit on Nikon D750. It adds great value in Natural Photography by adding dramatic effects through controlling light intensity from low to higher or higher to low range with just one filter being installed on the lens.

From the packaging and presentation to the build quality and functionality, this is a very solid purchase. I am very pleased with this filter and plan to order more from K&F Concept in the future.

I've used it once and I paired it with a 10 stop ND filter with this and I was able to set my camera set at 30 seconds, f11 and ISO 50 in the middle of the day but with the 10 stop I could only get it to 10 seconds, f11, ISO 50. I was surprised to see that when I got home to edit the photos there was no noticeable loss in sharpness with both ND filters on and this being a variable ND filter they're notoriously known to be less sharp than a constant ND filter. I can't wait to test this out on a waterfall but being that it's summer in San Diego right now I'll have to wait to try it out but along the coast I prefer the 10 stop ND filter and being able to drag that shutter longer. The front of this variable ND filter is quite large so your lens hood won't fit on there which can be an issue with unwanted lens flares but the K&F 10 stop ND filter I used with this you're able to mount the lens hood still. I received this filter free of charge to test it out so take my review with a grain of salt but if you do choose to get this I highly recommend getting a 10 stop as well because you'll be limited to 2-3 second shutter speeds with this alone at it's darkest setting in the middle of the day where the sun is bright like it is here in Southern California. I forgot to mention that there are notches on the side and tells you the minimum - maximum darkness and each stop between so there isn't any guess work involved but I do like the fact that I was able to set my settings I wanted and just rotated the front element until my camera read that I was properly exposed.

this is perfect if you take photos during peak sunlight. It basically gives your camera sunglasses. the filter quality is great and doesn't degrade the quality of your photo. If you've ever taking a photo outside and everything looked dark then you need an ND filter. I used this on the RF35mm f1.8 and noticed a little vignetting but this can be corrected in post. Since it's variable you can adjust the filter on the fly depending on how much light there is. The adjustment goes completely around so if you spin it all the way one way it'll take you from light to dark since there's no hard stop. It also comes with its own hard case so you can store it away in your camera bag without worry.

It's a very good variable ND filter, very useful and the images are clear. Used it when we went to Great Falls MD to take pictures of waterfalls.

I'm just a beginning photographer and am taking classes at my local community college (which I highly recommend for anyone else starting out like I am). I have an assignment for a long exposure photograph which most of the class is going to do at night. I wanted to try something different so I bought this ND filter for my Canon EF 17-40mm f/4L lens and I'm really happy with it. It worked exactly as I had hoped and I was able to get a picture of a nearby artificial waterfall in bright light with a 30 second exposure. The water has a nice creamy texture to it, but the rest of the image is sharp.

I wish the adjustment worked a little better with clear stops and the inability to go beyond Min and Max. I also can't remove the hood once the filter is on because there is a small rim that extends beyond the edge of the lens. Other than that, I'm very happy with this filter.
