14 ELEMENTS / 10 GROUPS
6 FUNCTIONAL ZOOM GROUPS
DESIGN f = 56.70-194.34 mm
MODELED f/3.563-f/4.977
2 ASPHERICAL SURFACES (1 ELEMENT)
G4 INNER FOCUS / G2 OIS
Focus MechanismModeled inner focus: G4 alone moves toward the object, with near positions inferred from Fujifilm’s 1.1 m minimum focus at each zoom station. The patent identifies G2 as the stabilization group; lateral stabilization motion is not modeled.
