I sent video on this issue to Fujifilm Indonesia to point out what I mean with 28mm f2.2 after zoom in zoom out. I also present my problem of battery problem which is not even a bar nor red alert before it completely loss power. They ask me to send it back to Fujifilm to be checked and recalibrate. They also will try to reinstall the firmware step by step from fw v1.00 until the latest v2.00 to see if it is a firmware issue only. I will comeback after they inform me what is wrong with the X10. However X10 is still a good camera for trip companion.
