I have this seemingly excellent 210 N f8 that I wish to use on a shift-stitch device for landscape. This will require to alter the lens by removing the shutter blades or preventing that they can close, and to build a special adapter because the FF distance of the Mamiya 7 is some 3,5 mm shorter than the standard M645 mount. Or maybe machine the lens mount, or graft the lens elements in another lens like the plain 210mm for 645, if any of that is possible with a reasonable expense of work. But before anything is attempted that will destroy the lens as far as it's initial use is concerned, I wish I could check if the lens image circle will fit within the shift device, because this lens has a special design with small front and a large rear element. Is there any way to open the shutter by an electrical means so that it will stay open? I don't want to test before I know what I am doing. I noticed on the wiring diagram that there are two contacts for magnets, one is for the open position and another one for the closed position. This is probably for the B pose. But there are also other contacts for shutter control. Well, I suspect that what I am asking won't work if the lens is not coupled to the camera, but maybe there is a repairman trick to open the lens to see through it for inspection or bench calibration? And if all of that is impossible anyway, it is always interesting to talk about it.
