16 IMAGING ELEMENTS / 12 GROUPS + PROTECTIVE MENISCUS
2 FLUORITE / 4 ED (PRODUCTION SPECIFICATION)
600mm f/4 (MARKETED)
f = 587.816 mm / F/4.08 (MODEL)
4.4 m MFD
Focus MechanismPUBLISHED internal focus: cemented negative G2 (L21+L22) translates imageward by 15.559 mm; D11 increases 17.545→33.104 mm while D14 decreases 45.385→29.826 mm, conserving D11+D14=62.930 mm. The source close state gives d0=3930.900 mm from object to S1 and β=-0.145; source-plane normalization gives 4.400 m to the focal plane. The rear image spacing is fixed.
