Sony 24 - 70mm f/2.8 Vario-Sonnar ZA Digital SLR 0.25x Zoom Lens with Super Sonic Wave Motor

Key Features

• Compact Design, All-Around Versatility: This superb 24-70mm zoom lens is an excellent choice for a wide range of photo applications - a lens you can put on and leave on, providing large-aperture brightness that's easy to carry (35mm equivalent: 36-105mm)
• Superior Large-Aperture Performance: Like other large-aperture Carl Zeiss lens designs, this f2.8 24-70mm zoom lens is simply magnificent in its ability to capture brilliant high-resolution images in low-light conditions requiring fully open aperture
• In-Camera Image Stabilization: A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony a system DSLR - and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms
• SSM (Super Sonic wave Motor): Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied
• Carl Zeiss T Coating: Coated optics were pioneered by Carl Zeiss - and this superb lens features T (T-Star) coating that virtually eliminates the lens flare, internal reflection and light scattering that can otherwise occur at glass-to-air surfaces
• Multi-Element Design: The SAL-2470Z is designed with 17 lens elements in 13 groups, including 2 aspherical elements and 2 ED glass elements. Floating motion between the third and fourth groups of lens elements helps compensate for any aberrations caused by the zooming action of the lens
• Glass-Molded Aspherical Lens Elements: These precision lens elements correct distortion for sharper, more visually accurate images across the entire zoom range of the lens
• ED (Extra-low Dispersion) Glass: Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used in Carl Zeiss lenses to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images
