K&F Concept 可調式ND2-ND400濾鏡 37mm

Swapping between ND2 and ND400 is so smooth I barely have to fiddle with the ring, and the included microfiber cloth came in handy right out of the box. The 37mm size fits my compact lens perfectly for bright daylight shots.

Took this 37mm filter out for a long exposure test on a sunny day, and the ND2-ND400 range gave me plenty of room to slow the shutter without any harsh color shift. The included microfiber cloth came in handy after a few smudges, and the ring turns smoothly enough to dial in the exact density I need

I was worried about color cast with a variable ND, but this filter stays neutral even at the denser settings. The included cleaning cloth is a nice bonus, and the smooth adjustment ring makes it easy to dial in the perfect exposure. It’s a solid upgrade for my 37mm lens kit.
