Leica filter system

[Zaradashte]

Hello everybody! I just got a Sumicron lens 50/2 black for my M6. I am planning to buy B+W uv filter for it, but I was confused to see -on the lens- the letter E39. Do you think any screw 39 filter would fit? Or does leica have there own system?
Thank you all in advance.

E39 refers to standard 39mm filters. I use standard B+W 39mm's on new lenses and on my collapsible Summicron from the 50's.

E39 is the standard screw fitting.

Cheers,

E.
