BRAUN Smooth Kính lọc ND-Vario 37 mm

The variable control from 2 to 8 stops is incredibly smooth—I dialed in exactly the blur I wanted for a waterfall shot without fumbling with stacked filters. It’s become a permanent part of my bag for daytime long exposures.

The build quality is solid, and the combination with a polarizing filter is a clever touch—cuts reflections while controlling light. I’ve been able to get smooth waterfalls in bright sunlight by adjusting the stops easily on the fly.

The variable 2 to 8 stops are super handy when I'm shooting in mixed daylight, though the adjustment ring feels a bit stiffer than I'd like mid-frame. Still, the polarizing combo cuts glare nicely and gives me that shallow depth-of-field control without swapping lenses.
