I dunno if I'd ever risk being out in bad weather with a camera even if it was weather proof!
In case you've never seen it - the 7d was pretty tough and the 7d2 is supposed to have better weatherproofing
It's not the most mature video but despite hitting it with a van a few times, freezing it and cooking it and setting it on fire etc it still worked. I don't think a bit of rain would do much
