the reason i bring it up is that, when comparing the m43 vs. nex, even though dof and iso differences are only about a stop, the two systems are the same price, so choosing nex for that extra stop still makes sense. but ff systems are WAY more expensive, so that extra stop and a half of dof and iso doesn't seem to have proportionate value.
