Commercial grade semiconductors are spec'd to operate over the range of 0-50C, and that's it. Going outside those parameters can possibly give "unexpected" results... Even if you test one example of a camera, or even 100, and it happens to work at -10C, that doesn't mean all of them will, as the components are ONLY specified to work at 0-50C...unless EVERY component/camera is screened to operate over a new temperature range (varying the voltage over it's specified range as well), you can't guarantee compliant operation. I happen to have a thermal chamber (-35 to +150C), and for a marginal fee, I'd be happy to test someone's digital camera ;-) Austin - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
