Over the last few days we have seen reports from photographers who had an overheating warning icon appear on the camera display when shooting with the Sony a9 in warmer weather or indoors. It appears that in none of the reported cases the camera actually overheated and shut down and it's Sony's overheating warning function that is a little bit overzealous.
Sony has now fixed the problem with firmware version 1. 01 for the Sony Alpha A9. In the change log it simply says 'This utility updates the camera firmware to version 1. 01 and improves the overheating warning functionality. ' You can select your operating system and download the firmware from the Sony support website now.
Have you had issues with the a9's overheating warning? Has the problem been solved by the new firmware? Let us know in the comments.
