Great filter!
Ever since I started doing bulb exposures, my variable ND filter of choice was Vivitar. It worked great over the years, but I needed a new filter. Since I also own a K&F Concept tripod and they treated me well, I decided to give this filter a try. What's cooler than an ND filter and circular polarizer in one?! And I'm glad I did! This filter works incredibly well. With my old ND filter, I had to stack a separate circular polarizer on top, which would lead to vignetting on my widest shots. With the K&F Concept 2-in-1 filter, this no longer seems to be a problem at 18mm. At 10mm I noticed a very slight vignetting which is almost imperceptible. But it' is definitely a huge improvement over filter stacking. Although it may require 2 hands, this filter is very easy to adjust. It also feels well built and sturdy. All in all, this filter was well worth the money invested.
