ALL SPHERICAL
G2 OPTICAL IMAGE STABILIZATION
PUBLISHED INFINITY-FOCUS ZOOM STATES ONLY
Focus MechanismNO_INTERNAL_RECONSTRUCTION. The patent publishes infinity-focus zoom spacings and states that G5 moves imageward for close focus, but it provides no close-focus spacing row or travel. The production minimum-focus distance is retained only as catalog metadata; every authored var pair is identical between infinity and close.
