   Isn't it more about being caught out in the rain, rather than setting off to shoot in it?

 PS. How many pros shoot Pentax?

When you get caught in the rain, do you not put your gear in your bag?  It appears that most anecdotes are about perception rather than real requirements, which was my point. I have been caught in the rain, I have been shooting on the beach (sand), my lenses have seen frost and snow. Any lenses got damaged from any of that? No...

And, I bet one of the three people who shoot with Pentax is an eccentric pro.
