原来过热是这么回事啊

*If the same part of your skin touches the camera for a long period of time while using the camera, even if the camera does not feel hot to the touch, it may cause symptoms of a low-temperature burn such as redness or blistering.

并不是机器过热，是怕人的皮肤长时间接触温暖物体，造成低温烫伤
过热提示，其实是提示使用者小心低温烫伤？

a7m2也会有新版的固件吗？
