Focus Mechanism

PUBLISHED: surfaces 1–13 translate together toward the object for focus. The 1.5 m model state uses the published Table 8 wide/tele shifts of 4.694/22.040 mm; the 92.433 mm mid shift of 9.458720 mm is code-evaluated from the same published mechanism at U=1500 mm. The inferred STO, G4, and BFD remain fixed; patent U is object-to-image distance and is not silently equated to the product MFD reference plane.
