Okko Pro / ND64 (6級) 中性密度濾鏡 40.5mm

I was worried about color shifts with a 6-stop ND, but this filter keeps everything looking natural even in harsh midday light. Threaded on smoothly to my lens and the 40.5mm size was exactly as described, no vignetting at all. Finally got those silky waterfall shots I've been chasing.

Perfectly sharp with zero color cast — exactly what you’d want for long exposure work. The 6-stop reduction lets me shoot waterfalls at f/11 in broad daylight, and the brass ring doesn’t stick or cross-thread.

I’ve been using it for long-exposure shots by the coast and the 6-stop reduction is spot on—no weird color cast in the highlights or shadows. It threads onto the lens smoothly and feels solid, which is exactly what I hoped for.
