I'll be darned
with all the controversy over NEX cameras overheating in video mode I thought the other night I'd see what mine would do. I have a 5N and left the kit lens on running the video at it's highest rate and size. Had the battery at 88% when I started and in "auto" exposure mode. At 15:20 the heat symbol come on the LCD. It ran 29:50 then shut off. I consider that quite acceptable. Room was about 70 degrees F. I was using a 16gb Class 10 card.
