Sony announced the new RX10m4. It has 315-point phase detect system, 24 fps burst shooting and the usual 24-600mm lens. With big disappointment we have to tell that the A7III has not been announced today but I got an update saying the E-mount announcement will follow soon in October.
Note of apology on the one SR4 A7III rumor: I didn’t know for sure what would be announced today (a part of the last minute RX rumor). But the one source who said the A7III would be announced today was definitely wrong. The good news is that finally an E-mount announcement is coming soon anyway.
