12 PHYSICAL ELEMENTS / 10 GROUPS
PATENT f = 14.71-69.8725 mm
MARKETED 14.3-71.5 mm f/2.8-4.8
MODELED MAX APERTURE f/2.865-f/5.037
5 ASPHERICAL SURFACES
INFINITY-FOCUS ZOOM STATES ONLY
Focus MechanismPatent-published infinity zoom states only. GR4/G8 is the axial focusing group, but no numerical close-focus spacing is published; no internal focus reconstruction is authored, and every focus pair is identical. The 0.35 m closeFocusM value records the marketed minimum macro distance rather than a modeled close-focus state.
