Sony a9 Testing Posted by Sony Addict on Wednesday, May 31, 2017

Earlier today I shot the Sony a9 consistently for 2 hrs 39 minutes and 19 seconds before killing a fresh battery that started at 100%. I live streamed about 30 minutes of the test past the one hour mark to show that the camera was still fully functional and to demonstrate how the 20 fps burst rate works on the Sony a9. It was 93 degrees Fahrenheit when I started the test and around 84 degrees when the testing ended. My testing leads me to believe that the cameras that we are seeing overheating are the result of a manufacture defect, which we can’t judge the size of yet. The cameras that failed were used in cooler weather and under less demanding conditions. Hopefully Sony will comment on the failures, because a camera that functions fully today could experience failure tomorrow if there is an issue with the thermal paste/grease being used since it drys out as the camera ages and losses efficiency. I also created a mini video of the Sony a9’s burst performance that you can see below.
