Recently, I asked about using the Nikon NiMH battery pack in my F5. I received many private e-mails, all positive. I really appreciate the time and effort that went into sending all those e-mails. Thanks. However, the pack and charger is still a LOT of money. Then today, I saw what might be a compromise: NiMH AA batteries. I received a catalog that contains four NiMH AA cells plus a charger for $38. Now, it is only an overnight charger, but has anyone out there ever tried something like this ($76 for eight batteries plus two chargers is a whole lot better than over $400 for the Nikon system)? Thanks, Colin
