| 14 ELEMENTS / 10 GROUPS |
| DESIGN f = 24.70–67.87 mm |
| DESIGN F/2.91 |
| 5 ASPHERICAL SURFACES / 3 ELEMENTS |
| 2 ED (INFERRED) |
Published infinity and near-distance (165 mm) spacing rows at wide/middle/tele. G5 and G6 move independently objectward. The 165 mm first-vertex reference is inferred from conjugate calculations; object-to-image endpoint is about 0.31946 m. Continuous zoom/focus interpolation is schematic, not a source cam or calibrated focus law.
