From a leaked video we can definitely confirm these specs:
– 24MP APSC sensor– max 4K 30P– got S-Log2, S-Log3 & HLG BUT no S-Cinetone– background defocus and product show function– 1x mic jack & 1x headphone jack– no Sony’s new menu system– 1x card slot– not using Sony NP-FZ100 battery
Still no info when Sony will now announce the new ZV-E10 :(
