At -47 degrees F, the R4s and 24mm worked perfectly even though it was mounted on a tripod for 2.5 hours. Upon returning to the car, I inadvertently exhaled into a scarf which diverted the moist air toward my glasses. The spectacle lenses were instantly covered a solid white frost and rendered useless. That is one time when you don't want to breath on a lens before cleaning it.
