Nano AR Coating
Sony’s Nano AR Coating with nano-precision structure contributes to high-quality images with
reduced ghosting and are. This proprietary Sony coating technology features aligned microscopic
asperities that reduce the eects of the reective interfacial boundary on the surface of the lens,
thus dramatically reducing the amount of undesirable reections entering the lens.
High-performance AF with enhanced object-tracking capabilities
Thanks to a new LSI drive circuit, the SAL70400G2 oers faster, more accurate autofocusing with
four times (TBD) faster object tracking performance than the current 70-400mm F4 – 5.6 G SSM lens.
The SSM (Super Sonic Wave Motor) takes advantage of piezoelectric elements that change shape
when voltage is applied to deliver ideal lens attributes such as a large rotational distance at low
speeds and swi start/stop response. The smooth, high-speed performance contributes to excellent
response when shooting moving subjects.
Uncommonly fast aperture.
The f/4-5.6 aperture enables shooting at higher shutter speeds to freeze sports action.
Super Telephoto Zoom.
This superb 70-400mm zoom lens is an excellent choice for a wide range of medium to long-distance
telephoto applications. (35mm equivalent when used with APS-C format cameras: 105-600mm.)
Superb exibility.
The 5.7x zoom range goes all the way from 70mm, suitable for portraits and other medium-angle
shots, to a super-telephoto 400mm.
G Series Optical Performance.
Sony's G-Series lenses are designed for maximum descriptive power, maintaining excellent peripheral
light characteristics and maximizing contrast even at the edges of the frame.
SSM (Super Sonic wave Motor).
SSM (Super Sonic wave Motor) is supremely responsive: faster, smoother, quieter focusing.
ED (Extra-low Dispersion)
Two ED (Extra-low Dispersion) glass elements minimize chromatic aberration for sharp, clear images
with well dened colors.
Superb Minimum Focusing Distance.
With the ability to focus as closely as 5 feet (1.5m), this telephoto lens also lets you move in for
dramatic shots of people, natural subjects and close-up details.
0.27x maximum magnication.
0.27x maximum magnication.
In-Camera Image Stabilization.
Works with the SteadyShot® image stabilization built into Sony α D-SLRs.
Three Focus Hold Buttons.
The lens enables to you rmly lock in focus for creative control. Focus range limiter can be set to
speed auto-focus response. Focus Hold also enables image preview with the α900 D-SLR.
Smooth Manual Focusing.
An easy-grip focus ring on the lens barrel gives you a solid hands-on" feel in manual focusing."
Multi-Element Design.
