I am in need of a little advice from either #Scandinavian Users and/or #Photographers.
I'm off with my Wife to Tromsø at the end of the month for a week. I want to take my digital SLR with me (Canon EOS 500D.. a bit long in the tooth but it does me)
Two questions. I have neither a fancy heated lens nor massive battery pack (I do have a few spare batteries though)
If I'm going to be out in sub zero temperatures (hopefully photographing some Aurora!!) how can I stop (a) my lens freezing over and (b) the cold draining my batteries too quickly?
is this even going to be an issue? I have seen USB powered "Dew heaters"?? but they too need to be powered by a battery pack. I'm puzzled if they'd even be any use.
Please boost for reach.
All info greatly appreciated.
