How long do I leave it in the bowl of rice? So this morning I wound up with my 2 month old 5-D mark II and 24-70 2.8L managing to stay outside during a heavy shower for about a half hour while I was inside. Once I went into emergency action mode, I immediately removed the battery, toweled it off, and researched what I should do next. I am not so worried about the lens, I know it is supposed to be moisture and dust sealed (just got it 3 days ago btw, awesome lens!) I racked it all the way out and toweled it off. The body has spent the day in a sealed bowl of rice, after drying it the best I could, there was no water in the battery compartment or the housing that I could see. So the question is, How long does it need to stay there? Thanks so much for your help, I hope this is a warning to everyone, it can happen, easily!
