I've been comparing the EOS-M to the Sony Nex series and IMHO this is what the EOS-M needs to be competitive, at least if you want to use manual focus lenses via an adapter:
Or you can ask ML team to make one for you. ML delivers much faster than Canon and with Canon, you can't be sure that they will do it because they "protect" their video sales.
i would expect ML to come out with something before canon too
ML to the resque...
