Focus MechanismInner focus: the patent moves the cemented G2 doublet (L4+L5) toward the object to focus closer. It publishes infinity states only, so no focus travel is modelled here; 1.5 m is Panasonic's production minimum focus. Zoom positions between the three printed stations follow a solved infinity cam in which G2 alone corrects the image-plane drift; it is not Panasonic's factory cam.
