This is really starting to get ridiculous, who needs a 1200 mm equivalent in a body that's impossible to hold still??
Superzoom compacts have moved away from usefulness to marketing gimmick IMHO.
There are several members on here who have bought and seem to like the SX50, and it is a 1200mm equivalent.
I also bought a SX50, it has the hybrid IS, and is quite usable. IQ starts to degrade noticeably above ISO 400. The previous Panasonic model was a straight f/2.8 lens but had less zoom.
I returned it because it was too difficult for me to press the buttons with my large fingers, so I decided to wait and see if a tough screen model arrives.
Here is a shot with it fully zoomed out at ISO 320
1/250 sec f/5.6
