Source 2:Reviewers just received the A7IV for testing in the field. Release date is more than likely September/October.
30MP sensor is correct.
Hi, I was told that the finalisation of the A7IV got postponed again due to current chip prices. As a result it’s expected the A7IV won’t be released in 2021. Some niche versions / variations of current camera models could be released instead in 2021.
