Is there a button (or custom function which could be assigned to some button) to auto-adjust exposure in Manual exposure mode on Sony Alpha 7?
I am a new A7 user, and didn't find one yet.
On other cameras (several Ricohs, for example) there always was a way to switch to a manual mode so shutter speed/f-stop value won't change all the time depending on how much of a cloudy sky you have in the frame, and after that you could point a lens into the asphalt road (relatively grey when not wet), press that button and it was kind of assurance you'll get properly exposed pictures for THIS kind of lighting. And then – going from let's say shadows to sunlit areas I'd press the same button again pointing to the asphalt (or my palm – about the same fake 18% grey from the exposure measuring point of view), and pressing it again to adjust to changed lighting.
Wondering if there is such a button on Sony A7 – to bring shutter speed (or auto-adjust ISO) to a proper value ones, and keep it at this level until that button is pressed again.
M
mode, the camera adjusts the exposure parameters (shutter, aperture, ISO) as if you were inP
mode, just once. It's sort of the inverse of an exposure lock which you turn on inP
mode. I find this quite convenient in many cases; the question is simply asking if the Sony A7 has a similar feature hidden somewhere.
