I just picked up a EX condition 500ELX from KEH for a decent price and these cool 9 volt adapters from this guy on ebay:


The only time I am *ever* going to use this is strictly for aerial work in that winding the film manually is a PITA. I do expect the temps to be as cold as 0F at times as most of these aerials are in Winter. The camera does come with the battery and charger but I expect fresh 9 volt batteries each flight to be a safer bet.

Is there anything else I should look out for?
