>>4272435You're just shooting a reliable brand. This stuff really isn't given. A buddy of mine shoots ricoh gr2, and they can be very susceptible to water. He goes through them regularly. Sometime, conditions are right, and he'll risk it. He's got a few, so the one that breaks just goes to a local repair shop. It costs, but I guess that they're experts on water damaged ricoh's now, lol.
From my own experience, freeze-proof can be very useful. My camera once soft locked from me shooting is blizzard with a zoom lens on. Zoom lenses pump a lot of air into the body, and that can cause issues. I left it in the bag for a while, it worked well after that. No weather sealing on the lens.
Another time I lost a lens. Again in freezing conditions. This time it was with a prime, weather sealed lens, but again no freeze-proof. No problems on location, but once I got back and tried to shoot with the same lens days after that, AF was busted. I also dropped my backpack that day, so I'm still not certain on what really caused it, but I've since move to only freeze-proof lenses, and I've had no problems since. Also, while we're at this subject, make sure to shoot with a filter on the lens when it's snowing. Usually useless hd filter can help a lot.
