At the moment i have: 5d mark with 24-70 2.8 and 70-200 2.8
It's awesome video quality, but almost not possible to shoot porn, as no auto focus.
(and all the rigs are to complicated).
So, i use it only for pictures and for video i use canon d10
It's overall good quality, but i can't look at this anymore, as it so flat, i want this "cinematic picture".
Checking now Sony a7s, it can be a good alternative.
Thanks
