Things got a little damp yesterday...
Not knowing how well the Sigma 120-300 S lens is weather sealed, I didn't want to take any chances so I fashioned a rain cover out of a giant 24"x20" ziploc style bag from the dollar store and held it together with duck tape.

Everything seems to have survived completely unscathed!

. I've been there with some plastic bags and rubber bands myself. I've since bought a cover but I know where you are coming from.
