On February 12 Olympus will announce the E-M1III. The full press text can already be read here. And two sources shared some additional tidbits:
E-M1iii will have the same 2.36M OLED EVF as the E-M5iii.
It is a small+light version E-M1X without grip and AI. The face detection improved over the E-M1X. CAF and focusing accuracy seem like better than E-M1Mark2 too.
