image above shows the current A7II
With the notable exception of the A9 Sony has been very quiet this year. Their short camera release cycle madness seems to be over. But luckily we will likely get a new camera at PhotoPlus (late October). SonyAlphaRumors got his hands on the possible camera specs:
6fps with mechanical shutter
ISO up to 51200 (expanded to ISO 204800)
693 phase detection AF (which is same as a9!!)
minimum focus sensitivity is EV-3
4k 30p recording
Not bad, and hopefully it will have the large A9 battery!
