DSC-HX100V is not exactly a sneeze is it?
"The most obvious of these changes include a 16MP 'Exmor R' back-illuminated CMOS sensor, 30x optical zoom and full HD 1080p video capture". " 27-810mm equivalent zoom lens and a compact camera-sized 1/2.3" CMOS sensor." Look at the zoom due to this small sized sensor plus it is a macro also. " 11 elements in 10 groups (including 1ED glass element and 1aspheric element". Look at the classification of the lens.
Beats most of the mainframes over two years old plus most of the separate lens available.
