Curious what lenses people who are flying the Sony a7s are using. I've been using my Canon L 24-105 with the metabones adapter. I'm testing out the Sony Vario 16-35 with the Movi m5 for handheld this week on a project and excited to see how well the autofocus works. Autofocus with the canon lenses is useless. Had a shoot last week and the internal 4K was great as it is with the shogun but when I went aerial everything came out soft though I haven't had a chance yet to test again (Washington rain). Thought maybe it was the IS? More testing needed, maybe tomorrow if the rain lets up.. at least enough not to soak the camera.
