A big plus for MFT for me is that the lenses are good and some are cheap. Primes from the 14mm f2.5 to 17, 25 and 45mm f1.8's are very reasonable new and very cheap used and there are cheap to reasonably priced zooms starting at 12 or 14mm which are good from wide open. For example I sold my 14mm f2.5 when I got the cheap 14-42mm Mega OIS as the tiny prime sized zoom is good at 14mm and the move from f2.5 with the prime to f3.5 with the zoom is no great loss to me.
