HX5V vs HX20V zoom
What is the longest digital lenth on these Sony (HX20/ 30V) cameras? I have a HX5V with a 10X optical zoom, but it's able to reach 57X (?) with the resolution set to VGA and digital zoom.
I know the quality isn't that good, but if I spot Bigfoot in the far off woods , I want to be able to take the pic.
Any other thoughts on the leap from the HX5V to HX20/30V?
