>>2614579I can't speak for the other cameras, but I hiked through Scotland and got rained on repeatedly and my E-M1 held up perfectly despite not using a weatherproof lens, it's a tough little camera and I'm very happy with it as far as build quality and sturdiness. My GR didn't miss a beat either, but that was inside a dry pocket most of the time. Honestly most cameras are surprisingly well sealed, at least in my experience I've never had problems with water damage and I'm not afraid of a little rain.
