The ExifTool version is probably not of interest to many.
You can see it in Help > About if you need to know the precise version.
OK so lets archive this feature request!
Note that I don't support ExifTool versions later than the one shipped with IMatch.
Phil may (and has so two times in recent months) introduce breaking changes which require changes in IMatch to keep things working.
Not very good when trying to maintain IMatch.

Perhaps on next release you would check if 12.30 will be OK.
I asked Phil to add recognition for Tokina 11-20 on 1
2 July. I see that 12.29 (IMatch using) was
released on 10 July.
12.30 was released on 13 August.
Thanks,
Aubrey.
