I was wondering if the focus distance could be checked for change from the last picture in the automatic intervalometer. To make it a change in focus detector? Or perhaps some other change.
Do any of these from funclist return the focus distance, DEF(GetLpfDistance, 0xFF93E3CC) or DEF(aDddLensidD, 0xFFA22970),
DEF(aDddLensinfoD, 0xFFA228F๐,DEF(aDddLpfdistance, 0xFFA22A0C),DEF(aGetLpfDistance, 0xFF93CFC0)
DEF(aGetLpfDistance_0, 0x004AB764),DEF(aSaveLpfDistance, 0xFF93CFA0),DEF(aSetLpfDistance, 0xFF93CFD0),DEF(evendproc_GetLpfDistance, 0xFF93E6E0),DEF(evendproc_LoadLpfDistance, 0xFF93E6A๐
?

The XTi / 400D Does write the distance into the EXIF. Does it say too much?

Curioser and curiouser.
I downloaded the free EXIFtool windows application from
http://www.sno.phy.queensu.ca/~phil/exiftool/index.html and dropped one of my XTi's RAW files taken with my EF-S 17-55 f/2.8 onto its icon to see the EXIF data.
My XTi is indeed writing the focus distance into the file! It has filled in both FocusDistanceUpper and FocusDistanceLower.
(later he says the values are exchanged upper for the lower)
I see that he also makes a .bat file to fix it.
Where he writes the line.
exiftool -n "-focusdistancelower<focusdistanceupper" "-focusdistanceupper<focusdistancelower" -if "$focusdistanceupper < $focusdistancelower" -r .
