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.
