Hey Stuart,
I am sure David or Josh will jump in and let you know what they have tried or are thinking of trying. They brought some sort of technical camera adapted to attach to an S2 with them on the New England fall foilage trip last fall. I used it with my S2 for a photo of a church to gain perspective control. It worked with no problem, but I can’t recall the brand. Sorry.
Good luck on your quest.
Mark
