I wonder if they created an /obsessed website section just to measure ad response rates. If so, that's good marketing technique. Also interesting that you can chat to a Pentax rep there for further details, again that's good sales technique.
Its officially confirmed ISO 80-51200, however, anything below ISO 100 and above ISO 12,800 is really software-driven "amplification".
Hardcopy magazines, especially monthlies, tend to have fairly long advertisement proof submission cut-off deadlines, so the ad may well have been accurate at point of submission.
ISO 51,200, especially, looks like a final touch Pentax put in just for marketing bragging rights.... I wouldn't know what to do with it, other than test shots just to try it out.
