R8 overheating

rsb816 — Thu, 17 Aug 2023 00:38:06 GMT

My new R8 starts to overheat when using it in warm to hot temperatures. I am not using the video setting at all just still photos. The temperature gauge starts to show up in the view finder after a short bit of time and once or twice it went all the way into the red zone. Once I was out in about 90+ degrees and today was out in 80's, very sunny and some humidity but has happened a few times. I am starting to worry that this will become a very big problem and altho I have heard this could happen when using the video I have not seen any information on this when just shooting photos. Is this normal?(altho should def NOT be normal!) but suggestions are welcome. Thanks!

The manual seems to suggest that extended live view shooting can cause overheating.

What’s the difference between shooting in Live View and recording video with an MILC body? There isn’t that much of a difference as far as the electronics are concerned. The image sensor is constantly powered up, which can produce significant heat.

How well protected is the camera from direct sunlight? Is the camera sitting on a tripod in the direct sun while it is powered up?

Is the camera allowed to shut-off its rear display between shots? Do you allow the camera to cool itself off?

I would imagine that there would be some more heat generated during video recording than in live view shooting, due to the memory card being written to constantly.

Was using Live View but not consistently and yes, turned it off when not using. Just seems to come on very quickly when hot outside. Was out in the desert a few weeks ago after just getting this camera and went into the red zone pretty quickly. I heard of the over heating issue but was pretty surprised to see this as not shooting video but yes, utilizing live view here and there. Very upsetting as I am really enjoying this camera as my first foray into mirrorless. I will be mindful of this issue and hopefully not have any serious issues with it. Thank you to all who took the time to answer my novice question!

What do you have the camera sleep time set to? Have you tried making that time shorter?

Just looked and yup, was staying on a bit long so I shortened it. Thank you so much for the suggestion!

Greetings,

This is something I'd pay close attention to. Especially with a new camera. Sun exposure as Waddizzle mentions is absolutely something which can contribute to heat generation, as does extended video shooting. For still images, I've never had a heat issue. My 6D2 visited Montana in summer and the desert in Palm Springs. The R5 C has a fan so it's not a good candidate for comparison. I would not expect a camera to overheat in 90* weather unless it was stationary in direct sun. The R8 is fairly compact. I've not held one so it might be possible but should only occur rarely if ever.

Hi! I agree here but I have read around that it can get hot with using the live view screen. Again. It seems to happen quite quickly once the temp gauge goes on. I guess I’ll monitor it a bit and see. Taking it out on a trip this week and see how it goes. Thank you for the suggestion. 😊

It's been happening on my R8 recently. The weather is warmer, and I left the camera in the shade til it recovered when I'd see the icon. Sometimes I find a series of shots turned out white, which maybe came from overheating when I was ignoring the icon, vs. simple buffer overflow.

I just put in a Lexar '800x' 128M SD card before I noticed it, so I wonder if it could be related, since it's a new card I'm trying.

Hi! So I posted this a few months ago and I have to say that the problem did not get any better with all the suggestions. Recently sold the R8 back to the store and bought an R6Mii and so so so happy I switched. The R8 is a toy compared to the R6 and although I am not a professional by any means I have no regrets about upgrading my camera body. There is no comparison.

The light weight keeps the R8 in play for me, when I get shoulder strain from lifting R6 and glass. Speaking of which, make sure to try an L lens too, if you haven't yet. 🙂

Hah! yes the R8 was definitely lighter. We hike a lot so I use a capture clip from Peak Design to carry my camera and that helps take some of the pressure off. The RF 24-105 L is on my list. THANKS!
