14 ELEMENTS / 12 GROUPS
f = 14.42–29.10 mm
F/4.0 (CONSTANT)
2ω ≈ 115.4° (WIDE)
4 ASPHERICAL SURFACES / 4 ED ELEMENTS
Focus MechanismInternal focus: G4 (single element L41) moves toward the image (patent ¶0092). The patent tabulates infinity only; close-focus D3/D4 are calculated so the paraxial conjugate sits at the 0.28 m production MFD, giving L41 travel of 0.52 mm (W), 0.75 mm (M) and 1.07 mm (T).
