The OM-D looks perfect on paper especially the new IBIS for video. However be aware: IBIS won't work for MF lenses on video.
This is the second time Olympus does not tell some critical details. When the EPL1 was out and everybody was excited about its IBIS, I bought one and only to find out it did not work for video.
In my earlier article, I said that OM-D still hunt for AF too much to be useful for video. Some friends argued that they would never use AF for video in the first place. Well, if that's the case, then I guess they would mostly use old MF lenses and they are out of luck again. It's a big NO to me to take a tripod for a camera who's whole point is about portability.
