truth to be told, with m4/3 you can't really go wide without some serious planing/gear. you also don't have the radio flash system of canon/nikon. Or the fully flip out screen of sony. The flash thing is a serious issue if you're doing any sort of stuff outdoor, indoor is easier to deal with because we'll rarely need HSS indoor, but out door where it's run and gun trying to kill the ambient light, you might run into some issue.Just about everything I own is considered by many to be the poor cousins of equivalent superior products, be it cars, cameras, tools, whatever. The funny thing is that all of these seem to perform as well as, if not better, than the so-called superior products. 'Superior' products often get their status due to marketing, not necessarily because they are inherently superior.
and this is the only small camera body with IBIS, if you really want to go small, the sony NEX is there, I have the NEX 5 sitting next to my P-EM2, and there's not much different in size. high end NEX use sony alpha flash system, the odin is there but it's very very expensive. Best system right now bars none is sony, if you have a ton of spare cash, they have some of the best lens and if you're willing to drop some serious dough, the radio flash system by odin is on par with canon.
