Product Description
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) autofocus is fast, accurate, and quiet.
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 autofocus 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.
