The only issue I have with mine is that Canon's flashes won't meter properly with FD lenses mounted via adapter, so you have to use manual flash. I can't figure out why.
AF is slow, but very workable in most circumstances. It's not a sports camera certainly, but neither is a NEX.

The 22mm pancake on the EOS M has about the same field of view of a 35mm lens on FF, so I bet a lot of optical hotshoe finders for Olympus, Panasonic, Leica, Bessa, Contax, etc., would work just fine. I have the Olympus VF-1 paired with the 17mm 1.8 on my Oly E-P3 and it works great and even has bright lines . The 17mm on M4/3 is equal to 34mm FF coverage.
