Eighteen elements in 14 groups (5 ED elements). Nine rounded aperture blades. The 77mm filter thread. At 1,300g the lens is heavy. Minimum focus distance of 1.5m. SWM (Silent Wave Motor) for fast, quiet AF. IF (Internal Focus). Two-ring design: separate zoom ring and focus ring ('Two Touch'). f/2.8 constant aperture. Full-frame coverage. Nikon F D-type mount.
The 'Two Touch' designation refers to the two-ring design (separate zoom and focus rings) of the AF-S version, versus the earlier AF push-pull 'One Touch' design. The AF-S SWM provides faster, quieter AF than the screwdrive AF-D predecessor. The 5 ED elements provide chromatic aberration control at the 200mm f/2.8 end.
On the used market the Nikon AF-S 80-200mm f/2.8D IF-ED is affordable as a vintage Nikon FX telephoto zoom. Condition checks: SWM AF response, 77mm front element for marks, zoom ring smoothness. Note: 'Two Touch' AF-S has two rings. Compatible with all Nikon F-mount FX bodies.
