Promaster 9566 77mm 可變中性密度濾鏡 | ND濾鏡 | 9566 | 1.3-8.6 級

I was skeptical about a variable ND at this price point, but the 1.3-8.6 stop range gives me perfect control for long exposures in bright sunlight. The ring turns smoothly without any of the dreaded X-pattern crosshatching I've seen in cheaper filters.

This variable ND filter covers a huge range, from 3 to 400 stops, so I haven't needed to swap filters while shooting outside. It adjusts smoothly without any weird color cast in my test shots.

Swapping between different light conditions on a recent outdoor shoot was a breeze thanks to this filter's smooth 1.3-8.6 stop range. I was surprised how little color cast there is even at the densest settings.
