17 ELEMENTS / 11 GROUPS
DESIGN 203.00-776.00 mm
F/6.42-9.18 (DESIGN)
3 × 497816-CLASS LOW-DISPERSION ELEMENTS
L2 TRANSVERSE IS / L5 FOCUS UNIT
Focus MechanismOnly infinity-focus zoom spacings are published. L5 focuses imageward, but its finite-focus positions are unpublished, so focus travel is not modeled. The production minimum focus distance at 200 mm is 0.8 m.
