No one has mentioned batteries. It's a sore subject with me. My fujifilm uses the double A batts and I learned to get organized with them. I set up a series of compartments marked, discharge to charge, and charged. As it was explained to me (and seems to work)you have to completely discharge your AA batts to get them to charge enough to work more than a short while. There is a setting on the camera that will completely discharge them and then when they are charged they keep the charge longer.
I haven't used the lithium batts(very costly)but may give them a try on the next camera.
