I just had one day in London on Monday. Naturally it rained the whole day. I didn't hesitate. Finding a dry spot to change film was a challenge but otherwise the most annoying thing for me was that I was constantly wiping the filter with a lens cloth because of all the water drops on it. Seemed like every shot I had to take one, then clean, take one, then clean! Camera worked fine though. I had my Canon 5D with the 16-35L as well and it worked well also. I knew it would work though as I have used it in rain and snow before. I wasn't sure about the Leica but as I was in London an extra day just for photography, I wasn't going to go home empty handed!!!

So you didn't have a hood in front of the filter?

I like to give my Ms a good soak once in a while.
