I'm using an a7sii, with 85 lens, and Ronin M. I'm shooting two people wrestling. I'm having all types of problems focusing because the wrestling is dynamic so there is a fair amount of movement. Ultimately, the focus drifts off and then finds itself after a few seconds, but this severely compromises the film.
My settings
F/2.8, shutter 100, continuous focus, wide, face recognition on
If I was simply using the camera on its own, I would hold the shutter button until focus is reached and I could move around, but this is impossible with the Ronin because you are using both hands to hold the gimbal. I don't have $2,000 for some follow focus attachment so what suggestions would you have for such a project?
Another point is that face recognition is great when your subject is facing you directly, but in my scenario, I'm often shooting the tops/backs/sides of the faces, so the focus won't immediately recognize that its a face to focus on. Should I switch to a wide lens like a 35? Any suggestions?
