Superb IQ but problematic AF and MF. If they fix the AF issue I'll probably get it when the 18-55/2.8-4 OIS is launched.

I am not sure if there is a possibility to "fix the AF issue", it does not seem to be software related. It would need a new design of the camera's AF and of the lenses.

We are talking about contrast detection AF here. As far as the camera is concerned this is merely a question of software algorithms and CPU speed. The software algorithms can always be improved.

The lens AF is certainly limited by the AF motor. The AF motor "feels" a bit conventional and nowhere as smooth as in (many) MFT lenses.

With camera there are two things - algorithms quality & speed of algorithm execution.

Only first can be improved via firmware, while second usually requires sensor and/or processor upgrade.



Oly advertised that they gained AF speed with extra processor & double FPS sensor readout.



But lens will always set a limit how fast things would be.
