K&F XB41 67mm Variable ND&CPL Filter 2 in 1 Function Nano Coating No “X” cross
After researching, I decided to get this variable filter. I\'ll tried the cheaper filters and realized for variable filters, you have to get a good quality filter.This filter works great, the fader works well versus the other ones I tried. I used it on my a6000 and it help me take better pictures with a lower f stop, giving me a more creamy picture. Definitely recommend on investing for this!
