You're absolutely right. At those temperatures the air is extremely dry and static discharge will be a problem also. Yes, I could use the ETRSi, but it would be nice to override the usual operation of the SQ-am. Wether the back counts the frames or not is less of a problem, as long as I can advance the film very carefully and slow and cock the shutter. Also the SQ-am has a prism-finder with an exposure meter built in which is handy in some situations.
