I have a Sony a77 as use as my backup. I was shooting with it a few days ago when all of a sudden a Camera Err came up. I turned the camera off then turned it back on. Seemed fine - took a picture then get Camera Err again. Turn camera off, turn back on, look at playback, image is there. I have not update this camera in a long time. It was a primary camera until I upgraded to a full frame Sony. I did a lot of shooting with the a77, is possible it has just seen its time?
