Promaster 5645 49mm 可變ND - HGX Prime（1.3 - 8 級）

I shoot video alongside photography, so the 1.3 to 8 stop range on this 49mm filter is exactly what I needed for tricky daylight scenes. It's smooth to turn and I haven't noticed any color cast, even when I crank it to the darker end.

This filter lets me dial in exposure perfectly without swapping glass on a hike. I love that it goes down to just 1.3 stops, so it’s usable even in softer light. No visible color cast in my test shots so far.

I was worried about color casts with variable NDs, but this one stays neutral even at 8 stops. The hard stop at the end of the range is a nice touch, prevents accidental over-darkening.
