I absolutely love having magic lantern on my 70D but until the overheating issue is resolved I can't risk it. I keep reading responses saying that its just the readout display being wrong due to yadayadayada. In the last four weeks I covered several concerts and before running the lantern on it I had no issue with overheating and the camera shutting down. but i did have trouble with focusing, hence the magic. Now with the lantern installed I only got half way through the concert when it over heated reading 70C. The camera was hot in my hand and I took the battery out and it was real hot. Putting another batt in seemed to cool it down a touch, enough to run a while longer before over heating again. There is absolutely an issue with the temperature when running magic lantern on the 70D. I have it on a t2i and it runs all day flawlessly no over heating or anything. Unfortunately I will have to remove the lantern for now. I hope that the devs can address this problem. 70d does not over heat when running without the magic of the lantern. Thanks for all the hard work guys.
