Amita,
Damp weather is not a threat to the lens. As long as it's not left out in the rain you'll be ok. :-)

Subject: AF lenses for astrophotography?
Is it possible to use an AF lens in the cold and damp for long periods of
time without damaging the electronics? I want to get rid of an MF lens I
don't like and never use, and the only reason I can think of to keep it is
for astrophotography. I was thinking of using the Sigma 20mm EX for this
purpose instead, but I don't want to do it if it's going to damage the lens.
Thanks, Amita
