Thanks Moose's advice.
Video shooting is a new task for me and I have to learn more about it.
Recently, I joined an video shooting related safety at work with training
department of my working company. I found the official video production
team in my working company that they use Sony A7 for video shooting with
Zeiss Cine-lens. Yup, they use MF focus.
Video shooting will be a gimmick for me so that I won't invest for
professional video shooting stuffs. I probably go to buy some accessories
for my Olympus M4/3 system for video shooting.
Cheers,
Michael
