The HS-10's difficulty in use is overstated IF you have any background using cameras in a mode other than Auto or Program priority. Indeed, they are no more difficult to use than the FZ-35. That said, if you tend to want a camera that will be used more in Auto than in, say, PASM... than, the FZ-35 is your baby.
