I think the electronics are well protected inside the lens. I've had both my sigma EX 70-200/2.8 and my FA*400/5.6 out on a tripod all night, to shoot something in the morning twilight. On two occasions, the FA experienced a light drizzle so that the whole lens barrel was wet when I woke up, but to no ill effect. The MZ-S that was attached to it was fine too. :-)

I'll second what Jostein said. Shouldn't be a problem unless it's a
downpour. And what would you see in the heavens, but clouds then...?
I was just thinking of dew. I've only been shooting AF lenses for about 9
months and I don't know how much they can tolerate yet. I'm used to the old
lenses that you could use to hammer tent pegs if you had to. ;)
Thanks, Amita
