Do you expect to shoot in foul weather a lot??? The Sony NX70U is rainproof (not submersible.) It can handle 32-104 degrees.
Or you can attach one of those camping chair clamp-on umberellas to your tripod to keep your camera dry/shaded. It saved my T3i (and me) from baking a couple of weeks ago on an all day shoot in the sun.
Without a lot more information it might be hard to give you a better answer than this.
