Can anyone tell me what happened here

Note the arrows pointing out random lines on this picture. This has not happened on any other pictures I have taken before or since.

I did experience this once and attributed the fault to a badly seating sd card. In my case it was not the fault of the card and I had to send the camera away to have the contacts cleaned.

i would say its something with the sensor,like dirt or malfunstion at these specific spots.Try clealing your sensor if possible otherwise if problem persists maybe you should send your camera for fixing

Not sure, but that boy sure looks guilty. Sorry about your camera troubles!
