Right. I didn't really pose the question. I'm testing the Sony A7R2 at the moment. I have tested the Sony A7S. I'm wondering what other documentary filmmakers have experienced using either or both cameras. Not planning to shoot in 4K though I would like to own the camera that allows for 4K on my next shoot. Shooting interviews, landscape/beauty. All in Belize for this project. Would love recommendations for lens that don't lose focus. As much flexibility as possible, of course. Thanks for your response.
