Finally, a filter that doesn't mess with my color balance—the IR suppression makes a noticeable difference in long exposures. The glass feels incredibly solid and well-crafted, and it's easy to clean when dust gets on it.

I was worried about color shift with long exposures, but the IR suppression keeps everything neutral even at 16 stops. The glass is flawlessly polished, and it threads onto my lens without any binding.
