PM UV HGX Prime 77mm Filter

I was skeptical about filter glass making a difference, but the clarity on this one is immediately noticeable. The individually ground and polished surface seems to let through more light without any haze.

Took these filters out for a shoot in some dusty conditions and the coating really does repel dirt—barely needed a wipe between shots. The image clarity through the glass is noticeably better than my old budget filter.

Finally, a filter that doesn't introduce glare or soften my sharpest primes—the multicoating really does repel smudges and dirt. It’s ground and polished so precisely that there’s zero color shift, even against a bright sky. I’ve had it for a month and haven’t had to clean it once.
