>>3762844They're both 1/4 and I bought them in 49mm for my Sony 55mm f/1.8. The regular pro mist is definitely more defined than the black pro mist in normal usage, and it adds a bit of haziness to everything. The black pro mist mostly works with bright lights / specular lights. To be honest, I haven't used them a ton, but I also haven't been shooting a ton (got them both a month or two before COVID hit so I haven't been out as much).
It's also kind of annoying how they put these reflection artifacts in the shot unless you take a lot of care to avoid them. But shooting directly into lights is the whole point, and it makes that more difficult. See pic related, it's that blue eye-shaped thing on the brick. That's with a black pro mist.
