I took a Photo using the Pentax AF201 to auto flash, the camera set in P mode, and it took an image at iso 80.

How is this possible? I thought ISO couldn’t go below 100.?!

Extended ISO 64 and 80

Where'd you pull that out of???

EXIF in Lightroom catalog. It seems bright scenes wide open the camera will pull ISO below 100. I have several marked at 64 and 80.

Interesting. Are you on auto-ISO? But I would still suspect that an iso of 64 or 80 is emulated to stop overexposure.
