Thanks. I was actually looking at the c100 w/ dual-pixel AF as well but the lack of 4k and slow motion was a deal breaker for me. Although I really like the colors.
The fs700 does have continuous AF in video as well (don't know which AF is better but would rather have it than not), but supposedly only for sony lenses. I'm guessing it's not possible to fool the camera into thinking it's working with a canon lens?
