NYC, NY (PRWEB) February 25, 2013
B&H Photo Video is pleased to share with the photography community the release of the Sony 70-400mm f/4-5.6 G2 super telephoto zoom lens , a superb zoom lens, for a wide range of medium to long distance telephoto applications. (35mm equivalent when used with APS-C format cameras: 105-600mm.)
High-performance AF with enhanced object-tracking capabilities
Thanks to a new LSI drive circuit, the Sony SAL 70-400 G2 lens 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.
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.
Uncommonly fast aperture
The f/4-5.6 aperture enables shooting at higher shutter speeds to freeze sports action.
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.
The 5.7x zoom range goes all the way from 70mm, suitable for portraits and other medium-angle shots, to a super-telephoto 400mm.
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.
In-Camera Image Stabilization.
Works with the SteadyShot image stabilization built into Sony α DSLRs.
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 α99 DSLR.
Smooth Manual Focusing
An easy-grip focus ring on the lens barrel gives you a solid hands-on" feel in manual focusing.
The Sony SAL 70400 incorporates 18 elements in 12 groups for high optical precision from the center of the image all the way to the corners.
Focus is accomplished by moving an internal element group, so focus is faster.
SSM (Super Sonic wave Motor) is supremely responsive: faster, smoother, quieter focusing.
Two ED (Extra-low Dispersion) glass elements minimize chromatic aberration for sharp, clear
images with well defined colors.
Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect. The Sony 70-400mm lens features nine aperture blades.
Works with Optional Teleconverters
Compatible with optional Sony SAL14TC (1.4x) which extends focal length to 560mm (35mm equivalent when used with APS-C format cameras: 840mm) and SAL20TC (2.0x) teleconverters which extends focal length to 800mm (35mm equivalent when used with APS-C format cameras: 1200mm). Teleconverters are compatible with manual focus only.
Supplied accessories. Carrying case, lens caps and petal shaped lens hood.
