Re: How to Stream Longer than 30 minutes with Canon M50 with autofocus, NO capture card!!

I will let you ask the question in a ML forum.  I will pass.  You must have me mixed up with those who have argued that DSLRs can overheat when used as video cameras.  

 

I simply asked a simple question.  If there is no problem with rising temperatures, then why is the temperature display seemingly highlighted as a warning?  I think it is orange because the displayed temperature is far outside of the manufacturer recommended areas of safe operation.


Or you just ask at ML forum why they use orange at 50 degrees Celsius for 7D, instead of guessing.

I have already said that I will pass.  I asked you what does it mean?  It is YOUR camera.  YOU explain it.

40 minutes of raw video. Reformatted the card four times. Reached 58 degrees Celsius. Seems hard to reach the internal heat warning indicator if the ambient temperature is around 24 degrees Celsius.

I suggest you combine forces with several other posters and establish your own laboratory, as the hardware limits of photographic gear is your primary interest. You can conduct various stress tests and other arcane measurements on camera bodies so that people whose interest in photography is mostly limited to the range of stress on comonents, chips, screens and buttons have a source of reliable info. There are engineering enthusiasts whose photographic interests don't include photography beyond the hardware side of things. For example, many people seem only interested in the number of times the shutter button has been pressed or how much heat a chip can take before failing. That's where you fit in. Best of luck.

You could just have sent me a PM instead Smiley LOL

@Waddizzle is it bad to think anything in your opinion? Better just pretend that you know it, like you do?

 

I "think" because I've seen this on a Sony camera once, and never on a Canon. On the Sony it's a warning and then a shutdown. Makes sense?

There is a warning and if you continue past that the camera will turn off Live view/video. From Canon and about 5D III:

 

Q4. Can my camera be damaged if I continue shooting while the high internal temperature warning indicator is displayed?

A4. No, the camera will not be damaged.

@Waddizzle
You are confusing "operating temperature" (environment / ambient temperature) with "internal temperature". 55C is the internal temperature.

@Peter
ML may not show a correct temperature: https://www.magiclantern.fm/forum/index.php?topic=9673.0 - the OP saw "80C" but it was recorded as 60C in EXIF.

@Peter, thank you, this is really good to know!

 

I shoot with a Ninja V on the EOS R, and maybe because the encoding is done on an external device I really never saw any kind of warning. The longest video I've shot was about 1.5 hours.
