Short answer - focus performance tends to leave a bit to be desired as cameras go smaller. (Though this can -for some subjects - be compensated for by focusing on the place the action is going to be in advance.)
Also, long - as in really long - lenses are hard to come by in MFT. Most useful for wildlife.

- slantyyz 10y agoThe often mocked Nikon 1 series is generally considered to have the best all-around PDAF of mirrorless cameras. It can track about the same as a DSLR (definitely faster than a 5D1, possibly faster than a 5D2). It has a weaker native lens selection than M43 but it has a 70-300mm lens that translates to 190-810mm (factoring 2.7 crop factor) that birders love. It can also use adapted F mount lenses with decently fast AF (center point only). On the other hand, the N1 series has so many other weaknesses (like being massively overpriced for what you're getting) that it's not a great system for most people.
