Promaster 77mm 可変NDフィルター エクストリーム - HGX Prime（5.3～12段階）

I was worried about color shift with this many stops, but the image stays neutral even at the darkest setting. The hard stop at each end of the ring makes adjusting exposure mid-shot feel precise and reliable.

The color cast is virtually nonexistent even at the darkest settings, which is rare for a variable ND. I’ve been using it for long exposure shots of moving water and the clarity is impressive.

Finally a variable ND that doesn't shift the color cast even at the highest density. I was able to get silky waterfall shots at f/11 in midday sun without any weird cross-hatching. This is exactly what I needed for long exposure landscapes.
