I have stumbled on a Micro Four Thirds setup that will actually ride in my shirt pocket like a compact camera. The Lumix GF3 body was only $85 at KEH Camera Brokers. I already had the little 12-32mm pancake lens. For once, I'm not mad about a lens being all plastic, because that compact and light lens makes it small enough to go in the document pocket of my gun burka.
The NEX-5T isn't much bigger, and sports an APS-C sensor rather than Micro Four Thirds, but the bigger sensor needs bigger glass, and the smallest zoom lens for the E mount is the 16-50 PZ, and it weighs almost as much by itself as the whole GF3 and lens combo.
The pancake collapsible 12-32mm isn't exactly a superzoom, but it'll snap a picture of a car parked on the other side of the street, which is about all the zoom I usually need.
