I went on the Saturday with a 1-day-old 5D3, and got royally rained on. I trusted the weather sealing. As far as i know, it held up.
Hi...
I just had a look at your Abbey Photos and some of your rodeo pics - your 5D mk III shots are great. Can't knock your 5D II or 7D shots either. You would have seen my rainy pic on the Sunday at the Abbey, below.
