A source told me this:
Sony A7sII successor and 12-24mm f/2.8 GM will be presented to the press and store managers on June 26th.
IMPORTANT: It’s yet not clear if on June 26 the Sony A7sII successor will also be officially presented to the general public or if there will be a short period of NDA agreement for the press and store managers. Usually Sony does make the new camera info public disclosure on the same day. But I got no information yet if that’s the case again with the A7sII successor. I still got no specs but Sony told us that it will have at least 4k120p, 10bit 4:2:2 and similar A9II AF performance.
One more thing: The source didn’t get any info yet about that second Full Frame camera that was recently registered in China and USA. It may be that this camera will be announced a couple of weeks later as I reported previously.
