How can anyone make a sensible response to such a question when there hasn't been one single review of a production camera, and the images published by Panasonic so far don't seem that special?
I can't see many people justifying it as an upgrade to their current FZ10. There are some nice features, but not enough difference.
For an FZ1/2 owner the differences might be tempting enough.
Butfor these folk andfor anyone in the market for a new camera, they shouldn't pay any attention to what has been said or reported so far, they need to see some production reviews and samples.
