Okko Pro / ND1000 (10 توقف) كثافة محايدة 40.5 مم

I was worried a 10-stop filter would leave a color cast, but this one keeps the blues and greens looking true. Even at f/16 in harsh sunlight, my long exposures came out clean and sharp.

Shot some waterfalls at midday and the 10-stop cut through the glare beautifully, giving me a full 30-second exposure without any colour shift. The threading on this 40.5mm ring is smooth, no jamming, and the glass feels solid. Exactly what I needed for silky water shots.

I've been using this for long exposure shots of moving water and the color cast is practically nonexistent. The filter threads smoothly onto my lens without any binding.
