Can you believe how utterly INCOMPETENT Sony have been?
The A7 mark3 which took the FF market with a storm could have been released already in 2015.
https://www.sonyalpharumors.com/backstage-story-sony-developed-low-pixel-a99ii-version/THESE MOTHERFUCKERS SAT ON THIS SENSOR FOR 3 YEARS AND DID NOTHING WITH IT.
IT JUST SAT THERE IN THEIR LABORATORY FOR 3 YEARS DOING NOTHING.
The public didn't see this sensor until 2018 in the A7 mark3.
In reality the A99 mark2 had prototypes as early as 2015, and one of the prototypes had the A7 mark3 sensor.
These assholes have the best technology in their laboratories, and they do nothing playing with prototype cameras.
