Okko Pro / ND64 (6級) 中性密度濾鏡 43mm

The glass is completely neutral, so my shots keep their true colour even with the heavy 6-stop cut. Threads on nice and smooth, and it's thin enough that I can stack it with a polariser without any vignetting.

Finally got to shoot wide open in full sun without blowing out highlights—this ND6 filter really does keep the colours true. It’s solidly built and threads onto my lens smoothly, no weird tint to fight in post.

The 6-stop reduction works perfectly for smoothing out water in daytime shots without introducing any color cast. For the price, it’s solidly built and threads onto my lens smoothly, though the glass could be a touch less reflective.
