Good-day,

I was wondering if anyone has experience with so called "extreme cards" (e.g., ScanDisk Extreme 512 MB CF Card) designed for operating in extreme hot or cold weather conditions? I would be interested in any experiences, opinions, suggestions and whatever else there may be to say.

If you want background as to the conditions I am operating in, see my other thread in this forum under the title "Macro->Nikon, Canon, Pentax->Bodies, Lenses". Just one note, though the furnace is operating at 700C (1300F), it is not extremely hot outside the furnace (relatively), and it is possible to cool the camera using a gas like Argon.

Thank you for your time.

Auf widersehen,

James
