"However, sales actually I do not fall for FZ series. High magnification zoom lens built-in camera is a big market in the worldwide. The time is considerably released the FZ200, but keep sales remain strong."
Thanks for the link. I found the article interesting; but painful to try and read the clumsy translation. In addition to the comment on the FZ200 selling well, he also mentioned that anything less than 10x zoom is hard to sell.
