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.

Features:

• 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.
