Very nice filter setup for mobile phones from K&F Concept
I really do like this K&F Concept variable ND filter with clip for my iPhone. The 58mm filter diameter is the perfect size to use for all three camera lenses without being burdensome. The quality of the K&F filter glass glare reduction is spot on with no weird spots or color shifts. The filter ring is metal and is easy to dial in the filter you need. The clamp is unexpectedly nice too it’s more of a parallel mounted clip (for a lack of a better description). The clip opens wide enough to allow for a phone case, and the retention holds firm all the way around the top or sides, even along the radius corner of the screen edge. The clip is probably the best functioning clip that I have ever experienced using.
