Would they be in order of their preference?
To af and touch af I have Panasonic 12-35 Mk1, is the one I plan to use in my Crane or run and shot.
I would like something to start to manual focus, with the panasonic I find it a hell, I do not know if the sigma would improve the focus by wire for panasonic. The option of Veydra or Rokinon / samyang Cinema is to have a prime with a repeatable focus for video.
