Newer generations of Optio S4
I am a amateur/hobbiest photograper. I have owned two Optio S cameras and have been very satisfied with them. My current camera is a S4. I would like to upgrade to a more current model that would be compatible with all the accessories that I have for this camera, i.e.: batteries, cases, chargers, etc. Does any know which of the more current Optio cameras are compatible?
