SAL500F40G
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 750mm focal length and ultrabright f4.0 aperture combine for superb results in virtually any light -and its improved high-speed SSM (Super Sonic wave Motor) auto-focus
is fast, accurate and quiet. Plus, the exclusive AR Nano Coating by on
lens surfaces cuts reflections for extremely low ghosting and flare.
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.
High Performance AF
Newly developed circuit board in the internal focusing mechanism achieves approx. 4 times
faster object tracking performance during autofocusing than lenses using conventional circuit
boards. This speed makes the lens perfect for capturing fast moving subjects like athletes and
wild animals, including birds.
Nano AR Coating
Sony’s Nano AR Coating with nano-precision structure contributes to high-quality images
with reduced ghosting and flare. This proprietary Sony coating technology features aligned
microscopic asperities that reduce the effects of the reflective interfacial boundary on the
surface of the lens, thus dramatically reducing the amount of undesirable reflections entering the
lens.
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.
Dust and moisture resistance
The dust and moisture resistance design makes this lens appropriate for heavy-duty outdoor use,
especially when combined with a DSLR that employs weather resistant measures.
Lightweight Design
A strong, light magnesium lens barrel makes shooting more comfortable even on long wildlife or
sports assignments.
