I remember years ago, Pop Photo had an article about a wildlife photographer shooting snow monkeys in the north islands of Japan. The Nikkormat EL had just come out, and many togs, including him, decried the short battery life of the camera in the cold, and so recommended using non battery dependent cameras.
Fast forward to today-the last time I did some sub zero shooting, the battery outlasted me
(I had a spare in my pocket ready to do the back and forth swap, but never used it). It is truly remarkable how far we have come with battery life in cameras, compared to the early all automatic slr days of 1973
