Promaster 5701 82mm 可變ND - HGX Prime (1.3 - 8級)

The range is the selling point here—going from 1.3 to 8 stops in one twist means I’ve stopped swapping filters mid-shoot. On an 82mm lens it feels solid, and the glass stays clear even at the darker end.

I was worried about color cast with variable NDs, but this one stays perfectly neutral even at the darker 8-stop end. The adjustable range from 1.3 to 8 stops is incredibly useful for controlling exposure without swapping filters.

This filter gave me exactly the smooth, silky long exposures I was after, and the 1.3 to 8-stop range covers everything from a slight blur to heavy motion. The 82mm threading fits my main lens perfectly without any vignetting.
