Sorry Raid. Didn't see it.
I have a Pentax digital that is weather resistant. I usually use if it will be really nasty but I have also used my M3 in really rotten weather as well.
With the M3 I hang it beneath my jacket/coat, pull it out and shoot, put it back. If it is pouring then I keep a towel handy to wipe things down.
Snow is not a real big deal unless it is the wet sloppy kind. Just remember, if it cold enough to snow you will likely fog the lens if you take it from cold to warm. When it is really cold I have a ziploc bag to put the camera in before I bring it in the house in the evening.
Leica claims that their digitals are sealed up well enough to put up with rainy weather but I've never tested that myself. A light drizzle sure. Heavy rain I'm not so confident.
You gotta love a fast lens;
It is almost as good as a fast horse!
