I've had several of these, including the Panasonic FZ-20, FZ-30, Canon S2 IS, and now the Fujifilm S9000. For me, the Panasonic's noise (30) and slow operation (20) ruled them out, even though in good light and with no rush, they produced EXCELLENT images. I really do want to stress that - when the light is good, these two were awesome cameras.
But the light, she plays the tricks, eh?

In difficult lighting situations these cameras had problems and the pictures often turned out too noisy to be acceptable.
The Canon S2 IS, I had for less than a month. Great movies, excellent swivel and tilt LCD screen, but it felt "cheap" and plastiky to me, and had no external flash hotshoe - I thought I'd be ok with that, but I wasn't.
So that lead me to the Fujifilm S9000. No image stabilization, and the pictures can seem soft, but the camera is fast in operation and the noise at any ISO below 800 is really quite good. At ISO 80 you can't, for all practical purposes, tell the difference between an image shot with the Fuji or a Canon Rebel XT DSLR. Compare an image from the Fuji at ISO 400 to one from the Panasonic FZ-30 at ISO 80 and you'll realize that Panasonic's OIS doesn't do a thing. The images will be about the same level of noise, and since the Fuji is shooting at 3 stops more speed, the lens shake is minimized equally well.
Oh, and the Fuji takes AA batteries.
But ya know what, my mantra is, "It's all good". There really aren't any magic cameras out there that do good in every situation, and all of the cameras out there will do ok in 80-90% of what you're shooting unless you're an action addict or someone who lives to photograph ants mating.
Which camera out there is the Best Big Zoom Camera, say in the
range of 10 to 12 Times Zoom? Thanks Bobby
