Okko Pro / ND64（6級）中性密度濾鏡 52mm

I've been using this 6-stop ND filter for long exposure shots of moving water, and the color cast is minimal—barely noticeable in post. The 52mm threading screws on smoothly without any binding.

Used this for a waterfall shot at midday and was surprised how sharp the image stayed even at f/8. The lack of color cast made post-processing much simpler than with my old filter.

Finally got this filter to try some long exposure shots in the middle of the day, and the 6-stop reduction let me drag the shutter without any color cast issues. The glass is crisp and doesn’t introduce any softness I can see.
