Got a question more about camera efficiency. Will a camera become less efficient regarding power usage over its lifetime based on age/use?
I have a few cameras of the same brand/model and age. They're all probably 5-6 years old (think I bought one in the summer/fall, and then the other two the next summer). They seem to use batteries at a different rate. For example, I changed batteries/cards about 3 weeks ago in all of them. Used the same brand of batteries. Checked two yesterday. One had about 900 pics and showed 85% battery. This was the oldest of the three. The other one had 300 pics and showed 10% battery. This was purchased after the other, but not sure on manufacture date. However, it has taken a lot more pics in it's lifetime than the first, due to being put out in more active spots.
