prosumer camcorders - sony vs canon autofocus
hopefully the larger DOF will be better than my m43 - tripod and don't zoom in too much - got it!
pj650v for $1050, G20 for $900 or x920 for $1000 will all have similar AF?
All 3 of those camcorders have an autofocus tracking feature. Just enable it, and then touch your subject on the LCD. The camera will then track the subject as he moves and stay focused on him.
It works quite well with my Canon Vixia HF G10. As far as whether one brand has an advantage over the other, who knows? I don't know if anyone has ever done such a comparison.
