quality wise, probably not. You cannot beat full frame. but... functional, using it in a flying platform... different story. DSLR is a ***** to control. Besides, it always has more weight.
And ... biggest problem with DSLR's in the air, is vibration and 'jellowing' (rolling shutter). For pictures, no problem, just set shutterspeed high... but with filming, what I read, it's a real problem. Next to the fact that controlling the camera, focus wise, is nearly impossible in the air. On the ground it's already difficult, using follow focus, LCD screens, it's still a hassle. I use OKII which is a great help for focus, gives ya electronic control, through the camera. Would be nice if that guy from OKII made it in WiFi format, but still...
the movies I saw from that Sony, are good enough for me btw... and probably for most customers also.
