Mike and fellow Nikonites,
The best I got of my N70 purchased 3 years ago is 18 rolls (all most all 36
exposures) using Panasonic CR123 Lithium cells. Of these around 60 shots
were with flash. Auto focus was used always along with fairly long shutter
speeds (slower than a second) sometimes. I was told that longer shutter
speeds drain batteries more. May be someone knowledgeable can confirm.
I got only about 10 rolls using Duracell but they were almost half the cost
compared to Panasonic cells.
Regards
