70D overheating

[Dr. Patricia farrell]

Yes, it is. I am so relieved and I really want to take video with this camera. Now it’s going to get mounted on a tripod with a fluid, video head and we’re off.

Hi guys, recently my Canon 70D has been behaving a a bad way. After 10 minutes filming, when I turn off and turn on the camera, I see purple, greenish colours on the lcd screen. When this happens and if I try to take pics, the photos also appear when I transfer the file to my computer. It’s usually a matter of turning it off four a couple of mins and then turn back on to get back to normal. The third time it happens which was yesterday, it took a whole day and only when I turned back on this morning it was normal. Canon tech support mention the fact that I use the camera a lot for filming and I’m in a very hot environment here in Brazil. And that’s problem while it’s experiencing some glitches.

I shot a 10 mins video inside my room with the air conditioning on and it was fine. I’m now afraid to even start filming with it again outside.

Have you guys experienced anything similar?

Thanks in advanced
Marcio

Hi Marcio,

I have not had the level of issues that you mentioned. My overheating 70D was becoming more and more consistent for me so I do not use it anymore as my primary camera.

My overheating issues may have been from a recording device which I had stacked under my battery pack. My shooting partner still uses his 70D and has great luck, but he does not stack an audio unit under his batt pack, which leads me to believe this may have been my problem.

I recently picked up a new MKII C100 and no longer have any problems. It has a built in fan to keep it cool. I use the 70D as a backup or b-cam. My primary purpose is video. I wish I had some helpful insight to share with you. I, too, would be worried about filming outside.

Best to you,

-Mark

Thanks for the reply Mark! Yea, it’s weird. I just had another 20 mins filming session with it and it behaved fine. I’m wondering if it’s because I was using some generic batteries as opposed to the canon one and it was overheating more than normal. From now on I’ll just use the canon battery to see what happens.

The MKII C100 looks hot man, I’d love to get my hands in one of those. I don’t use an audio unit so hopefully I’ll figure out a way of using the camera without causing this glitch.

I’ll experimenting using my iphone 6 whenever I can and keep the canon 70D for more special occasion.

Thanks for the input, I appreciate it.

3rd party batteries can cause problems. Additionally, cheap or slow recording media will cause your camera to heat up because the camera will have to fill up the buffer because the card isn’t able to write data fast enough. Cheaper cards (Transcend, Komputer Bay, etc) are far less stable than name brands like Sandisk, Lexar.

DSLR’s don’t have a fan. So if you’re shooting outside, in direct sunlight it’s going to heat up…potentially overheat too. Add to that the items listed above (3rd party batteries, slow media, etc) and you could be in for a world of hurt. Take a towel with you when you shoot outside to cover over the camera with when not in use. At one point with my 7D, we even used icepacks to help keep it cool. But there’s no great solution to dissipate heat with a DSLR. They’re just not made for video even though they’re capable of video.
