So I was shooting today at a beach in florida and I was shooting on no flash mode. It was all fine until my camera kept setting the shutter speed to 30 seconds and the shutter speed and fstop on the top display were flashing and wouldnt go away unless i turned the camera off and on again. I'm on vacation so I'd like to fix this problem asap. If you have any idea what may be causing this problem PLEASE let me know. Thanks!
