The PRO arm is brilliant. No doubt about that. Just to speak fairly about the G70x, however, I just finished 5 months on a show. We went from zooms, to master primes, to weird 200mm lenses with no matte box..... I never had to adjust the lift either. I think it's just a personal preference thing. I probably could have, and I'm sure there are operators that love to tweak all the time to get things just perfect, but I feel that's a statement more about the operator rather than his or her gear. I don't see my footsteps, and I've been specifically complimented by multiple DPs in the past about my lock-offs. Again, this is not a brag. I guess my point is, and this point has been made before, we the operators are what makes all the difference. Focus on your gear, and you'll always have shinier fancier gear. Focus on your operating and you'll be a better operator.
