بروماستر 72 مم IRND1000X (3.0) HGX Prime

I was worried about color cast with a 10-stop ND, but this filter keeps everything neutral. The dirt-repelling coating is a real bonus when I'm swapping filters on a dusty trail.

The ground and polished glass on this filter is noticeably clearer than the cheaper ones I’ve used, and it’s already handled a few smudges without leaving streaks. My long exposures came out perfectly neutral, with no weird color casts even in bright sunlight.

I’ve been using this filter for long exposure seascapes, and the infrared suppression really keeps the blacks clean and free of that weird magenta cast. It’s hefty but precise, and the coating makes wiping off salt spray a breeze.
