Leica E49 UVa II 超薄濾鏡，黑色

The slim profile is what sold me—it sits so flush on the lens that my hood still snaps on without any fuss, and the glass is crystal clear with zero color shift in my shots. UV haze reduction aside, it’s just a solid peace-of-mind layer that I forget is even there.

I was worried a filter would add glare, but the multicoating on this one handles bright sunlight beautifully. The slim aluminum ring means no vignetting on my wide lens, and it screws on buttery smooth. Exactly what I needed for straightforward lens protection.

The slim profile sits flush against my lens cap, so no annoying fiddling when swapping lenses on the go. UV haze is noticeably cut in bright mountain shots, and the coating makes smudges wipe off without a fight.
