The brilliant long-distance lens with wide aperture and fast auto-focus response. For definitive long-shot precision and spectacular portraits even in low light, this professional G-Series lens raises the standard of DLSR performance. Its 35mm-equivalent 450mm focal length and ultra-bright f2.8 aperture combine for superb results in virtually any light -- and its high-speed SSM (Super Sonic wave Motor) auto-focus is fast, accurate and quiet.
Feature List
SSM (Super Sonic wave Motor):
A built-in lens motor for faster automatic focusing with high torque at low speed, quick start/stop response, and quiet, smooth operation.

ED (Extra-low Dispersion) Glass:
Three precision ED Glass lenses correct chromatic aberrations to provide extremely sharp telephoto images distant subjects as well as dramatic sports close-ups.

Internal Focusing System:
Internal lens elements move, so the overall length does not change -- creating an auto-focus zoom lens that doesn’t affect the balance of your camera.

2 DMF (Direct Manual Focus) Modes:
Allow you to quickly revert to manual focus by just turning the manual focus ring of the lens.

Versatile Focus Hold:
Four focus hold buttons in different lens locations, plus electronic slider focus range selector switch.

Lightweight Design:
A strong, light magnesium lens barrel makes shooting more comfortable even on long wildlife or sports assignments.
