Leica UVa II Filter

I put the 39mm version on my vintage lens and it threads on smoothly without any binding. The build quality feels solid and the glass is perfectly clear, so it doesn't affect image quality at all.

I needed a 49mm filter to protect a new lens, and this one fit so precisely I barely felt I was adding anything to the front. The multicoating cuts reflection nicely without any color cast I can see. Simple, solid build—just what I hoped for.

The 46mm size threads on smoothly with no cross-threading issues, and the black finish matches my lens perfectly. It’s cut down flare noticeably in bright sunlight without affecting image sharpness.
