Focus MechanismCONSTRAINED_RECONSTRUCTION: rear G1 subgroup L4-L5 translates 8.59615 mm toward the object for the 1.5 m close state at the three published zoom control columns. The patent close-focus d9 row is inconsistent with its rigid-group mechanism by 0.00710 mm; d9 is corrected to 10.59521 / 24.64596 / 31.46770 mm so the d5+d9 sum remains constant at each control column. G2 and G3 remain at their published zoom positions during focus. Between source columns, the viewer's piecewise-linear spacing interpolation is visualization only and is not asserted as the actual Nikon cam law or an exact 1.5 m conjugate.
