For the record, I haven't used the as7. So don't have first hand experience. However, I looked at it heavily, and for wide angle, the white balance is not good from a custom standpoint. Canon is king for custom white balance. From everything I have heard, it won't work below 10 feet. The camera works well for macro with artificial light, and auto wb. But wide angle it struggles. This is why you don't see too many using it for video. Someone you might try is Kay Burn Lim. He is on Vimeo and Facebook. He has just left his Sony for a RED, but he is the only one I know of that has used it seriously. His macro work is beautiful with it. Haven't seen any of his wide angle. I would try to connect with him.
Hope that helps.
