Sony a7s shutter speed changing by him self...

[lucas paschoalick]

Hey friends,

I own a Sony Alpha 7s,

Sometimes the cam start to tilt and the shutter speed goes completely crazy, it starts to dance between two values like, 200/250, and when I tried to change it just keep dancing between some values.

This happens only with the config set to the front dial of the camera... In my case I use the Shutter, but if I change to aperture the same thing happens.

Another aspect is even if I go into the menu and lock the dials, it will keep changing.

This is a hardware or software issue? This is a common problem with this camera? There is a fix?

I'm in need of great help because there is no way to work with this error. ?

Thank you guys for the attention.
