In addition, something I may have missed in descriptions, and surely have in photos, MDx cameras had provision with that special plate and I have just realised film gate was modified to accept the marking strips. This breaks film rails and leaves substantial gap on both rails. While surely MD/MDa has been used by many for regular photography, I have to suspect exposed frames have visible soft edge in that area. Is this correct and is it annoying, if one were to print whole frame, no crop, especially with sprocket holes included?
I had an MDa coming earlier, but that deal fell through, seller pulled out at last minute. But my search continues and just now this little thing came up. Shooting super wide with it, to me mostly means while frame idea, at least on some shots. I may be better off with IG instead for planned application.
