There was a bonfire burning for us to cook sausages while we waited and waited and waited. 2 1/2 hours later when the air temperature had dropped to -20 deg C, we had the very good fortune to be able to witness sighting the Aurora Borealis. It was not a good show and it only lasted for 10 minutes, but I was very happy to see it and to capture an image or two.
How did the Fuji perform in -20 Deg C temperatures? Flawlessly - with no need to change the battery, everything worked just fine. I, on the other hand did not perform as well and needed some time to thaw out!
