I bought a Lumix FS30 recently. It has an 8x optical zoom which works great when taking pictures. However, I was recently on holidays and wanted to take some video with it, but the zoom does not work while filming. I had thought that this was a pretty basic function. So if I want to zoom in or out when taking a video I literally have to stop filming, zoom in or out, and start filming again -- it's ridiculous! Is this the same with all Lumix cameras? Or at least the same for other FS30s? I need to know if it's fault with my camera or not before I bring it in to them!!

Thanks
