Just an update. I took the camera in today and even though the issue occurred once or twice the tech said the camera was fine and the flash won't fire in the dark. It isn't supposed to do that. Couldn't give me an answer when I asked him why the camera even had a flash then.
I insisted it be sent to Sony to be looked at. If it comes back and they say no problems I am giving it to my granddaughter as an introductory camera. She has a great eye and loves to take pictures.
It won't fire in the dark? But I thought you said it was firing, just firing before the shutter?
Though, are you sure the flash was firing, Nd not just the AF-assist?
On some cameras, in the dark, the flash will give a quick burst to help out the auto focus.
But you still should get a correct exposure, because the meter should adjust.
