K&F XB41 67mm Variable ND&CPL Filter 2 in 1 Function Nano Coating No “X” cross
I Was Skeptical, It\'s Phenomenal.
I was really skeptical of this filter because of its price point. It\'s pretty fantastic on the A7iii and Sony 24-70 F/4.Not much color fringing, no real impact on sharpness, built well and a nice case. Wow.
