| 25 elements / 20 groups |
| Patent nd; Abbe numbers inferred |
| All spherical |
| Dual-group floating inner focus (G5 + G6) |
| In-barrel VR (L17 + L18 cemented doublet) |
| Centered VR configuration |
Patent G5/G6 floating focus: imageward travel is 1.39/9.708 mm at wide and 30.617/30.999 mm at tele. The 0.382 mm tele D38 change is relative group separation, not G6 travel. Near source figures describe about 0.98 m; VR lateral motion is not simulated.
