Sony Senior Manager Yutaka Iwatsuki just spilled out some bits about the future Sony A7sIII:
1) Mr. Yutaka said that “for time frame, it may require longer than you probably imagine”
2) This long waiting time is necessary because Sony wants to “go beyond the customers expectations”
3) A7sIII will not have 8K recording
Sony also made it clear they want to focus on FF and APS-C and they have no plan to go MF yet.
