Does anyone have experience using the extension tubes on the Zeiss 50mm Tuit (Fuji native mount) lens? If so, please share your experience (or better still, images) with this combination. Does it work with 11 and 16? Both together? Since the lens already goes to 1:1, presumably one can get greater magnification till you run out of working distance. But I'm only speculating...I would love to hear from anyone with experience combining them.
