I've been shooting Leicas in Afghanistan for six years. Unless you are intent on playing in the dust, or want to shoot endless pictures beneath hovering helicopters, there is no need to get worried. Just bring the camera you want to bring and take some simple precautions in transit and placky bags in case there is severe dust or sandstorms.

It comes down to carry and lens choice to me. My preference is RF for wide to normal and SLR for tele. You're shooting 24 & 50, so it would be the Leica and a zip lock bag for me. The F2 is bloody bulky and heavy. I'd back it up with the mju or a canon s100 and be happy. Shoot what you shoot.
