Either 4 AA or 2 of the other. > Personally I'm going to use AA NiMh. On the istD Cat Page_part2.pdf http://www.pentaxusa.com/docstore/index.cfm?show=122 it shows item #44 - CR2016 Battery (Compartment Open), which looks like a button-style battery of some sort. (Backup, for clock and settings perhaps?) By the way, I'll shell out cash for some lithiums, get two sets of NiMHs and always be able to buy alkalines at any corner store anywhere in the world (almost). Christian
