Leica E39 UVa II Filter (Black)

Finally, a filter that actually feels like it belongs on a Leica lens — the black ring matches the chrome perfectly and the glass is crystal clear. I’ve been using it for a week now with zero flare issues, and it’s nice knowing the front element is safe without any image degradation.

Mounting this on my 50mm f/2, the threading is butter-smooth and the black rim perfectly matches the lens barrel. Reduces glare on sunny walks without adding any visible color cast to my shots. Exactly the protection I wanted without sacrificing sharpness.

I've had this on my 35mm Summicron for a month now and the UV haze reduction is noticeable in bright coastal light, while the black rim doesn't add any distracting reflections. It's thin enough that I forget it's there, and the glass wipes clean without leaving streaks.
