One new source sent me this:
Good news! The a6700 will have focus stacking in camera! Really looking forward to it!
Let’s hope this one is spot on!
Reminder: The new High End APS-C camera will be announced next week on July 12. Specs and name are still not 100% confirmed. But it might be named A6700 and might use the same 26MP sensor of the FX30.
