The electronic viewfinder on the Sony RX-1, like the one on the NEX-7, has a sensor on it that tries to detect when youíve put the camera to your eye. Once it thinks thatís what youíve done, it turns on the EVF and turns off the LCD screen on the back of the camera. If youíre wearing a hat and leaning in close to the LCD screen trying to read the small type in bright light, the sensor can think youíre trying to look through the EVF, and it turns off the LCD.
Itís maddening sometimes. You try to read the LCD. It goes blank. You push your hat back on your head. It works until you want to read something on the left side of the screen. It goes blank again. You look for some place to put your hat. You finally end up putting it on the ground. You swear.
Today, I was playing that game with the RX-1, when I got an idea. I swiveled the EVF until it was pointing straight up. Problem solved.
