Thanks for the answers!

In digitalcameras there´s a great deal of tradeoffs between sensor size, optics and Price. I want to buy a superszoom with a mínimum of 12x to about 420mm eqiv and will use it a lot for videos, in fact, the only reason why I´m considering a digicam instead of a camcorder is the sensor size. After searching I found that the cameras with the proper optics and price usually have 1/2,3´sensors, for instance canon sx510 with 720mm, f/5,8 tele and a smaller but newer sensor. To compare it to my old A630 I wanted to know if the smaller sensor size has a big influence or not, my A630 has f/4,1 tele and the bigger sensor, the sx510 has f/5,8 tele (a whole fstop slower) and the smaller sensor, would in this case be a great difference when using both cameras in tele?
