Good day Mangusta
I really hope that you are still a contributor to this forum as I seriously need your help. I bought my wife a Pentax ist DL a few years ago and we are also struggling with batteries (alkaline/lithium/rechargeables etc) that simply will not power this unit. It is most frustrating to see the display panel always showing a "battery empty" message.
We are from Cape Town and will certainly be willing to compensate you for any help that you may be able to offer.
Hope to hear from you soon.
Best regards
Dirk du Plessis
