I have a Sony NEX 5N and noticed the overheating warning come up several times in the past and eventually the camera shuts down. I want to know if this problem occurs on any other models of Sony Mirrorless cameras? I don't take many videos however I spent the weekend at a Music Festival and ended up shooting several hours of video using my Fuji SL1000 Bridge Camera, which worked flawlessly on a tripod being left to record for upto an hour at a time. However the video quality isn't as good as the Sony with a nice lens. The main models I'm looking to get are the 5R, 5T, or A6000. If the A5100 had a hotshoe I'd consider that as well but off camera flash is too important to me.
