We all want many things in a m4/3 camera. Here is how I get some of them: Compactness: use small primes, not long or heavy zooms. Unobtrusiveness: ditto. Especially avoid zooms that telescope. Avoid changing lenses: choose several primes, fairly close in focal length,so that any one of them can be used as the "normal" lens until the time comes that it is convenient to change lenses. I use a 12-32, a 20 and a 45. Reduce weight: Distribute the weight. Carry a small extra lens or two,, in each slacks or jacket pocket, not in the same pocket and not in the camera case. A big error is trying to consolidate everything in one place. Distributed weight is much lighter and less onerous. Try a small lightweight camera case the simply holds your camera. Why add a pound or two pound or more, to what you are carrying? Or if possible avoid a camera case entirely.
