HC-V770 has been recently released so worth checking out.I find the Panasonic HC-V750 the best. It has "hybrid" OIS which is a mix of mechanical and electronic stabilisation. I find it perfect for handheld videoing. IMO it is better than the Sony system.
Zoom is 20x optical going to 50x Intelligent ( no picture degradation) and 1500x top!!
no, my hands are not steady as I stop to start filming after ether run or ski or bicycle or etc activity, so my HR is way above 120which sony model under $500 has the BOSS system?
if you got steady hands, even the panasonic v250 with 50x can be steady
