Fits perfectly

I have this ultra-low reflection uv filter in three sizes! It is very well made, easily threads on the lens, and provides great UV protection as well as preventing my actual lens from being scratched. Great value for the price! Picture quality is great through the filter. I use this filter for everything outdoors.

Excellent quality. the filter is very well made and the image rendering is excellent.

Mounted on my Fuji Xt-20 with the XF 18-55 f/2.8-4R LM OIS or the XC 50-230mm f/4.5-6.7 OIS II zoom with this filter allows me with a small investment to get excellent results.

The filter is very easy to screw on and off. Once screwed in, it stays firmly in place and is not likely to come off, so rotating the polarized lens is very simple.

In the field, it has given excellent results.

Excellent price and excellent quality without strange or loss of quality in the photos

Excellent also the metal ring that protects the filter well.

This K&F Concept Black Diffusion Filter creates a very, very cool dreamy effect while maintaining image sharpness. I use it with my Fuji X-T100, and I'm very happy with the results. The filter screws on perfectly (no issues with the filter body) and does not create vignetting even when used on my UV filter. The images I take with the filter are nice and clear, but with the dreamy, slightly grainy film effect that haze filters like this are supposed to give. I love that I can get the effect without applying any filters while editing. The filter also gives a softer effect to faces, so it's ideal for portraits. I use the 1/4 filter, so the effect is soft. The greater the number of filters, the greater the effect produced.

This filter is perfect for mirrorless digital cameras. It is continuously adjustable from ND2 to ND32 and the camera follows the viewing in real time.
I enthusiastically used this filter for detail photography in bright sunlight and with an open aperture, thereby reducing the brightness.
The workmanship and material quality is excellent, I don't have any complaints about the adjustment mechanism that other reviewers write about.
With me, he now regularly sits on my 18-55 Fujinon and in front of my Fuji XT-20 for cropping with an open aperture.

I'm excited.

5 stars for a reasonably priced product!

Got this for my X100F. The filter gives my photographs a natural film look that I can't achieve in Photoshop, which is exactly what I was looking for. The 1/8th was perfect for me because I wanted a very subtle but noticeable change.

This K&F Concept black diffusion filter creates a very, very cool dreamy effect while still keeping the picture in sharp focus. I'm using it with my Fuji X-T100, and I am super happy with the results. The filter screws on perfect (no issues with the body of it filter) and doesn't create any vignette-ing even when used over my UV filter.

The images I'm taking with the filter are nice and clear, but with the dreamy, slightly grainy film-like effect that mist filters like this are supposed to give. I love that I can get the effect without applying filters when editing. The filter also sort of gives a softer effect to faces, so it is great for portraits. I'm using the 1/4 filter, so the effect is gentle. The greater the number of the filter the greater the effect produced.
