Yes, focus totally bad. Have not ever updated firmware on this camera so probably not experiencing what you describe. I really appreciate the info re which battery you buy. I saw one on Amazon yesterday for $8 and thought I might purchase it. Since I haven't updated the firmware, I should be able to use it. Outside of the battery problem, I don't know what else could be wrong. It's such a great camera - I hate to lose it. Thanks for input.
