i have that tilt-shift-bellow( front only)called contax auto-bellow pc. i will use dslexchange adaptor. i will buy a second bellow and novoflex will add a novoflex-universal-mount. this will be done for the first time. so i can use any novoflex-camera-adapter. they cost 70 euros. orignal contax/yashica-combination used-there is a cable s37s for exposure-simulation. would be interesting if the cable could be used on a zeiss to contax/eos-combination. so one end must have canon-connector. i have tried out(not used) all kind of heads(enlarging/copylenses). its impressive. zoerk-multifocus-system is easier to handle and has more options. novoflex has ineresting multi-use shift/tilt-bellows.
