It's very interesting to see so many posts by people who left m4/3 for another system and then returned once again (sometimes twice or thrice!) to m4/3. This seems to happen quite regularly. Selling gear and then reacquiring it again (especially the exact same gear) can be a fairly costly process. Of course, if the replacement m4/3 bodies and lenses are different, then I guess there isn't too much lost - aside from losses attributable to the acquisition and subsequent sales of the other gear that was tried and given up. I think one can learn, vicariously, through observing this oft reported phenomenon and possibly save oneself from some time, effort, and expense. Reading numerous posts by those who have strayed away and then returned to m4/3 has helped keep me steady with my m4/3 gear (system lenses more than anything - as I do tend to move through m4/3 bodies fairly readily), even if I do dabble with other gear (on the side!)... I'm not leaving the m4/3 system. Not yet, anyway. Then again.... if the RX1 comes out as an RX2, with a built-in EVF, tilting LCD screen, and taking a rapidly growing system of interchangeable lenses... I may have to seriously rethink it all again.
