Is M4/3 being left behind ? Features-wise

Tough to be a manufacturer these days - AF that "couldn't be any faster" and they still need to improve it

Seriously, though, the lack of pro sports caliber AF tracking doesn't have any impact on my images. The tracking and single shot AF it does have is 'good enough' to get shots like this:



Is it really so far behind that you are ready to dismiss it? How many of your shots would actually benefit from phase detect AF (assuming it is faster!). I do expect that Oly will have a camera with phase detect on chip at some point, and the key advantages of Micro Four Thirds will still be:

Smallest system around

Benefits of having two manufacturers working in a common format

One single sensor size (from smallest body to largest) - no trade off between smaller size and compatibility with all bodies (EF, EF-S, EF-M, FX/DX/1, Sony A/E, etc.).

Lenses designed for CDAF (adding PDAF to the middle of the chip does not help with the fact that PDAF lenses have heavier/larger elements when using CDAF for things like face detection or corner to corner AF)
