NIKON AF-S ZOOM-NIKKOR 17-35mm f/2.8D IF-ED — Optical Cross-Section & Ray Tracing

Home / Lenses / Nikon / NIKON AF-S ZOOM-NIKKOR 17-35mm f/2.8D IF-EDNIKON AF-S ZOOM-NIKKOR 17-35mm f/2.8D IF-EDJP 2001-083421 A↗ — Naoko Fukuda
13 ELEMENTS / 10 GROUPS
17.50–34.00 mm DESIGN STATIONS
f/2.9 DESIGN
3 ASPHERICAL SURFACES
2 ED-CLASS COORDINATES
Focus MechanismFor close focus, G2F moves toward the image plane while the other groups stay fixed. Travel to 0.28 m is a constrained estimate at each zoom station; the patent does not publish close-focus spacings.
