I'm presuming he means that activating the sensor crop(4/3 image area mode) is a dive into the menu and not a simple one or two button process that can be done super fast on-the-fly in a run & gun situation. In other words, you're gonna have to stop what you're doing to activate it.
That's correct. It's not a terribly long process, perhaps 10 seconds once you're used to it, but it isn't an on-the-fly sort of thing.
