Sigma 77mm WR Protector Filter

I was a little skeptical about paying this much for a filter, but the coating really does make wiping off dust and smudges effortless. It sits flush on my lens and hasn’t affected image quality at all, which is exactly what I needed for peace of mind outdoors.

The WR coating genuinely works—I accidentally smudged the glass with my thumb while mounting it, and a quick breath and wipe cleared it right off without streaks. It's also reassuring to know the lens is shielded from dust and scratches during outdoor shoots, and the filter doesn't affect image shar

Installed this on my 24-70mm and immediately noticed how easy it is to wipe off smudges compared to my old filter. The WR coating really does make a difference with dust and fingerprints.
