Thanks for more very useful info.
Do you have any idea why we weren't able to reproduce the problem with our 80D?
I could try implementing your sequence blindly (without being able to test the before/after behavior, because, again, our 80D just works), but would very much prefer not to do that. Need to figure out how to reproduce the problem.

By the way, we have quite a few users with the Canon 80D body, and no one has reported this specific problem before. So we're not alone in not encountering this odd behavior.

Can you explain why the bodies (80d and 5dmk4) and lenses (Sigma and Canon) does not works as expected?
Can you explain why the 600D used the same lenses, computers, cables, works as expected?

One of the nice thing about technology is, that you do not have to speculate, but you can investigate why something works or not.

I am not a Canon developer, so I can not figure out how extensive the changes of the firmware is and what the implications is. I am the customer who figured out that something does'nt works as it should. You maybe, have more insight into the canon firmware and will be able to determine the problem better than me.

In general, i did not want to develop anything but just take pictures. That was the reason to buy a Software instead write or modify them.

I am not deep familar in develop Windows programs for camera's or lenses, but in firmware development for industrial applications since a few decates. I understand how software works and what parts of them are resposible for what. It's not Magic.

I also had not recomend using the methode i had descripted before. That's was a quick & dirty hack to find out, what the dslr doing under different Setup's - just drop and forget them anyway. It's your software, your business, your decision.


I will now solve "my problem" alone.

Thank you for the inspiring exchange of ideas.

I don't recall ever calling this "your problem". But fair enough.
Canon does not publish any documents that could give insight into its firmware's inner workings, so your guess is as good as mine. We don't have any inside on Canon firmware besides what we observed and reverse-engineered.

Well, i had implemented my final solution in the source of digicamcontrol, so a further discussion is not required.
Thanks for all.
