canon eos temp sensor

[dts350z]

The consensus on other forums is that the temp sensor in Canon EOS cameras is not measuring the sensor temp, but something else, perhaps the temp of the image processor chip?

 

If that is the case, how good is the correlation between that temp (whatever it is) and the sensor temp, for use in matching dark frame temp to light frames? 

 

There also doesn't seem to be an authoritative description of what causes the temp (in the EXIF data and BYEOS filenames) to go up. Long exposure, high iso, battery vs. AC supply, or only the read at the end of the exposure? 

 

Thanks,

It does not really mater.  Everything is relative.  Match your darks/lights with the same temperature source.  In this case the temperature reported in the EXIF data.

 

Hope this helps,
