It seems I must have been asleep when I typed in the shooting info.... :
Correct info is 7D with 100 f/2.8L macro, ISO 100, f/32, 1.3 sec. Can view all this in EXIF info embedded in file.
The main point I was trying to make here was my desire for max DOF (f/32) and good IQ (ISO 100), which required somewhat long shutter speed (1.3 sec). Fortunately, there was enough available light and no wind to do this.
