Thanks for the responses. When I say continuous AF, I don't mean the tracking that you need for sports and rapidly moving objects. During video when you move the camera from one part of a scene to another, there is a need to readjust the focus. One option is for you to explicitly engage the AF to do that, the other is that the camera refocuses automatically. With my GH1+20mm combo the refocusing was fairly slow, and you could notice in the video the lens hunting to get to the final focus point. Thats why I was wondering if things are any better with newer bodies. Typically in this case you are not really looking for lightening fast AF, but a reasonably quick and smooth transition to new focus area is needed. Similarly having a faster initial acquisition of focus is desired as well.
Video is not the main concern, but a reasonably smooth video experience is needed. The EOS-M + 22mm combo actually replaced my RX100. RX100 is a fantastic compact, but obviously still not at the same level as an APS-C sensor for low-light shots. The EOS M combo improves on that but in the process the video capability has been sacrificed. That's why I am looking to go back to m43 to retain a similar level of stills quality but gain on video performance. At the same time it is preferable to keep the form factor as small as possible. RX100 to EOS-M was already an increase. E-PL5 + 20mm would be similar size to EOS+22mm so if that could work well enough, I would be tempted to go that route. If not then the next one in line to consider would be the 17mm 1.8.
