the price difference is more than two and half times. I basically need more zooming power. One user review of v10 at an online shopping portal says that it can do very good low light shooting due to its some auto scene setting. Is it true? In that case I can compromise between full HD and HD recording. For my still photo I am very happy with my Panasonic FZ 100. In fact it gives me almost same result as my Nikon FM 10( Film camera).
