I've been googling around this topic quite a bit but wonder if there is anyone here who has experience of this type of photography? Or can point me in the right direction for some serious advice? I'm thinking in terms of buying or developing a system that would have commercial application. It must be possible to deliver ultra high-quality video made with lightweight m4/3 kit for lower costs than the established players charge for their big set-ups and still make a healthy profit. There may be a niche there somewhere. Many thanks in advance for your thoughts.
