Sony SAL-300F28G2 Marketing Specifications

SAL300F28G2
SSM (Super Sonic wave Motor)
Thanks to a new LSI drive circuit, the SAL-300F28GII oers faster, more accurate autofocusing with four times faster object tracking performance than the currently available 300mm F2.8 G SSM lens. The smooth, high-speed performance contributes to excellent response when shooting moving subjects.
Improved optical performance
The SAL-300F28GII is specically developed for digital photography. Its high-contrast design will keep pace with the ever-increasing pixel count of digital image sensors. Beautiful background blur, one of the features of the G lens series, is now even more beautiful thanks to optimizations that reduce spherical aberration.
Nano AR Coating with nano-precision structure
The SAL-300F28G features the same Nano AR Coating found on the SAL500F4G 500mm lens. This recently developed proprietary Sony coating technology sharply reduces the reection ratio to realize clear, crisp image quality with less are and ghost from internal reections.
Dust and moisture protection design
Designed with outdoor use in mind. The front and back of the unit, as well as the area around the focus ring, are specially constructed to help prevent water penetration. When used in combination with the SLT-A77 or SLT-A99, this lens contributes to a camera system that reliably withstands tough shooting environments.
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 aect 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 dierent 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.
