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.  
High-performance AF with enhanced object-tracking capabilities
Thanks to a new LSI drive circuit, the SAL70400G2 offers 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 swift 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 flexibility.  
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 defined 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 magnification.  
0.27x maximum magnification.  
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 firmly 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.
