bought the gradient filter because it was recommended to me by friends. After using it for a few weeks, I can say that I am more than happy with the sky or too dark foreground. This is where the filter shows its strengths. The filter can be easily placed in a suitable holder without the risk of it slipping out. This gives you beautiful images even with long-term exposure. To expand I will buy more filters from this brand later. I can give a clear buy recommendation!

use the filter both for shooting with DSLR and for long exposure during the day with the aperture open, especially when filming, it's just beautiful with the aperture open. The ring is easy to turn. However, the sound must be recorded externally as the ring silently clicks into the intended positions. The packaging is ideal for transport and also withstands the attacks of my 1 year old daughter. Image quality looks good. At least I couldn't see any tones or other disturbances, I'm very satisfied with the ND filter.

I have other K&F's and they all perform as advertised. This one is no different. Well made, good images, works as expected.
"Real" photographers, such as Rick Sammon can't say enough bad things about variable ND's. I have used them for years and never once was disappointed by them. The bad mouth guys are always complaining about the "X" issue. Yes, if you turn too far, you'll get an ugly X across your photo. Here's the secret which as served me well for a long, long time. You ready? "Don't turn it too far". I don't know why that is such a tough concept to master. Of course, the lazy manufacturers could help the situation by putting stops on the filters, but they seem to prefer the complaints to a simple, positive move. For my part, I help myself by gobbing on some white nail polish on the three points in question, so I can easily pick out the "too far" points. I can turn it down to focus/compose, then turn it up to where I want it and shoot. That beats the heck out of trying to shoot the image blindly, or repeatedly screwing and unscrewing the filter to get the shot arranged.
Really, a reasonable price, a little common sense, and you'll be good to go with this filter.
I hope you found this information useful and/or helpful.

The build quality and clarity on this filter is excellent. The adjustment ring is a little snug, but I expect that to loosen with time. I can't tell a difference between this filter and my higher-end ones.

Out of the box this filter is well made, threads on and adjusts smoothly. The optics are quality and I was pleased with the photos. I did experience some vignetting when pushed to the limits, but that might have been caused with me having the UV filter still attached and like I said that was at the very extreme end of the filter position. Very impressed with the filter and it's quality. The photos were F8, ISO 100 and 1/160,1/25 and 1.6 sec. Would buy again.

The filter works best if you have a lens that is greater than 35mm. When the lens is too wide angle is when you get the X looking area
