What's the m4/3 sister forum site to this one? I've tried a 4/3 forum, but it isn't very active. I'm mulling over adding a backup interchangeable kit that can take legacy glass. The camera will eventually be handed over to my son (whose 4 at the moment), whenever the next M is released (probably three to four years) at which point the M9 will become the second body. The Fuji systems are not an option, since I think the viewfinders will not hold up to the abuse dealt by a my son (though he hasn't yet dropped the 40D).
