Wim, I have never noticed this on my Canon cameras. Would I be correct in assuming that the Canon 5D MKII does not save changes to RAW files before saving?
Thanks, Pinhole

No, Canon camerasand in-camera processing are ok in this regard. Actually captured data are saved to the RAW files, although as with any camera some processing is done upon reading of th evalues from the sensor, amongst others, in order to cover for values overshooting on high contrast transitions (boundary effects). This is a fix for technical sensor limitations, however, nothing similar to postprocessing of the actual image data.
IOW, corrections for the limitations of sensor stored voltages and the A/D conversion processes, nothing else.
Kind regards, Wim
