I'd add - When you have things at default, the sonys make afc look much better. Panasonic needs to center weight as the default! - Try using 1-area af. Panasonic should probably label this as VIDEO FOCUS and have it as default or something for video shooting. That's if their AFC implementation of all the other settings are going to stay as flaky.  - AFC is mostly flaky in most other settings. This will need firmware support. Why? Because the problem isn't with the hardware. Photos
