SAL-300F28G 300mm f/2.8 G-Series Super Telephoto Specification

300mm f/2.8 G-Series Super Telephoto Lens

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.

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.
