18 ELEMENTS / 13 GROUPS
14mm f/1.4 (marketed)
f = 14.42mm / Fno 1.46 (Example 1)
3 ASPHERICAL ELEMENTS / 5 ASPHERICAL SURFACES
0.24m MFD / 0.11× (production)
Focus MechanismPUBLISHED rear-focus state: patent L2 (data surfaces 23–29A) translates toward the object; D22 5.08→4.08 mm and D29 2.20→3.21 mm. The patent's 240.532 mm row is preserved in the audit and treated as an image-plane-referenced total object distance/MFD because literal first-surface use contradicts the stated -0.1× conjugate.
