Any real measurement data on mirrorless sensor heating?

[Jim Kasson]

Ever wondered what happens to the image quality before it shuts down? I guess not; ignorance is bliss.

If you look at my tests you can see what happens. No need to guess. Caveat: I didn't test video.

It looks like the situation hasn't changed since I started to look into this a year ago; data on image quality degradation, due to sensor heating in e.g. live view and video modes, particularly for mirrorless cameras, is not available. Oodles of users reporting problems and user manuals warn of image degradation, but no hard data. For me, this is a major shortcoming of manufacturers, test houses and technical reviewers alike. If this situation doesn't change when I need to replace my DSLR, mirrorless cameras will be a no-go for me.

No-go it is, Rodger that. Over and out? Good.

You are ignoring the hard data that I've reported.

As predicted after many, many such episodes just like this.

I'm not, Jim, but your published data on mirrorless cameras is limited to a handful of Sony's, one Nikon and one Fujifilm, all higher-end, expensive cameras, none include video mode and most don't specify if the camera was in EVF or LCD mode and if they were in the worst case EVF or LCD mode. Yes, your blog gives me more info than any other source, but it's not giving me warm, fuzzy feelings about mirrorless, let alone mirrorless cameras that would be more in my price range.

Translation Jim (not that you need it):
”Your actual testing and actual data didn't state the results I wanted to hear before I asked the question.”
This behavior is well documented over the years here and elsewhere. Kudos for your hard work and for posting the results for others who take actual data seriously.

I think Jim can speak very well for himself, no need to continue your ramblings, Andrew. And yes, so far I didn't find the data I am looking for. Get over it and mind your own business.

I wonder, did you run that by Jeremy?

[digitaldog]

You wonder, indeed.

[Frans Waterlander]

You wonder, indeed.

I see; you are definitely not getting over it!

Nothing to get over.
I'm simply agreeing with you; you said you wonder, you said you guess. You wrote "presumably". Those statements are accurate.

[Frans Waterlander]

Isn't it interesting to see that the recently announced Canon R5 and R6 mirrorless cameras have significant overheating issues? Not only very limited video run times and long cooling down periods but also significant heating up when the cameras are switched on and not in video mode. But again, no image degradation data available.

If some data were provided by (fill in the blank) would you accept it?

[Frans Waterlander]

Very good, Andrew, less than 10 minutes response time, while you were off-line when I posted! Of course, your "response" is totally useless.

[digitaldog]

I didn't expect you could answer my question.

[Jeremy Roussak]

I wonder, did you run that by Jeremy?

Why should he do that? I moderate, I don't censor.

If you post in a public forum, anyone who, having registered, is permitted to post is of course free to comment. "Mind your own business" is a spectacularly silly comment in the circumstances.

How about repeated, personal attacks?

Indeed, just in this thread, thanks for pointing them out  :

I know you may have an issue with keeping on point, but I'm still looking for real measurement data, not snide remarks.

Do your homework and read the warnings in user manuals, mirrorless and DSLR's alike.

Logical thinking isn't your strong suit either, apparently.

Unless you can help to get answers, stop your rambling.
