@ismaelg. Mine doesn't report the focal length at all. The SR works fine, it's just that the focal length isn't reported
@Marc: I have been setting focal length for SR since I got my first non-DA/F lens, but the focal length does not show up in exif even if SR is activated. I check the exif on Lightroom just like ovim and there's no focal length reported. I am guessing that indeed firmware version 1.00 does not record focal length into exif from the SR.
I'm still waiting for possible "I screwed up my K100D because of firmware update" post
