Hoya 77mm Pro ND32 Filter

The glass is perfectly neutral with no color cast, which saved me so much time in post. It cuts exactly 5 stops as advertised, and my waterfalls look silky smooth even in harsh midday sun.

Finally got the long-exposure shots I've been chasing—the light reduction is spot-on and my skies stayed perfectly silky. Threads onto the lens smoothly, no vignetting even at wider apertures, which is exactly what I needed.

Finally a filter that doesn't introduce any color cast—the glass is crystal clear and the stops are dead accurate. I've used it for long-exposure waterfalls and the exposure metering was spot-on every shot. This is the first ND I've owned that feels genuinely precise without any guesswork.
