I got into M43 a while back, and built up a system of lenses as well as camera bodies. The Panasonic LX100 (and Leica Type 109) have come along, pretty much making me want to sell off my M43 system. After using M43, I came to the conclusion that (with the exception of use with a few pancakes) the portability of the camera body was kind of offset by the lens, and not really pocketable. This led me to go into the Fuji X system and the Sony A7. Of course, I know the primes of the M43 will be better than the LX100. But the LX100 is kind of pocketable. I'll be sadly selling on my M43 gear, so look out for some ads on here from me ! In an ironic way, I think a great new product like the LX100 has (somewhat to a small level) shot the M43 system in the foot. I think there will be some people out there who may no longer want to maintain an M43 system when they can get a compact M43 body with a built in zoom.
