I was happy with some compact kodak models, IIRC olympus used standards accumulators too, but i am not sure there are still selling on the market ?
Update:
I think Canon PowerShot A1400 is the most recent product that would fit my needs… wondering if there anything newer, or more sophisticated ?
Optical viewfinders don’t drain the batteries.
Well yeah, I’ve only seen digital viewfinders the last few years though.
