B&W 49mm 漸層減光鏡 ND 0.3-2x #501

The threads on this 49mm filter spin on smoothly without any binding, which surprised me given how slim the ring is. I've used it to even out a bright sky over a dark foreground and the transition looks completely natural in the final shots.

The graduated tint on this 49mm ND is perfectly smooth—no harsh line in my landscape shots. I’m getting clean exposures even with bright skies, and the filter threads on without any binding. Exactly what I needed for balancing light in my cityscape work.

I've been using this graduated ND to balance bright skies with darker foregrounds, and the 0.3 to 2x density range gives me plenty of control without making the image look unnatural. The glass is crystal clear with no color cast.
