I have update my f717 firmware or adjustment. The Sony Girl say that all camera may need to update. But, those selling now should be no problem.:thumbsup:
I also went to Sony center to upgrade my F717 firmware, all I can say is the staffs are extremely friendly and nice. The firmware upgrade process took about 5 minutes, and the lady did it right in front of the customer. At first I thought that she would align the laser so I took out the skylight filter for her convenience. However, the actual process did not even need to take off the lens cap! She just took out the battery/memory, removed a small plastic near the battery door, inserted a flex cable to that socket, and adjusted some setting on a handheld gadget which tied to the flex cable. And returned the F717 immediately to me right after that.
