Canon or Sony camera?

I just want to warn you over how much batteries are needed for mirrorless cameras, people carry bags of them just to live through a couple of days, if you are going to use it in remote places or in cold it can be a big challenge. I see in comparison Sony gets more shots and has inbuilt focus motor, but Canon is waterproof, and also imo this Sony doesn’t look as being comfortable for hand. I think for such purchase it’s better to go and try them both in shop.
