Yesterday’s huge firmware upgrades brought some good news. With the exception of the new A9 all A7II series camera do no more have the “Star Eater” issue. I expect the same fix will be available soon with firmware 1.02 for the A9 too.
One of the major improvement has been seen on the A6300. With the new firmware it takes more than double the time before it overheats in comparison to the older firmware.
