Sony Vario-Sonnar T* 24-70mm F2.8 ZA SSM II Overview

Manufacturer description: The new Vario-Sonnar T* 24-70mm F2.8 ZA SSM II standard zoom delivers significant improvements in image quality, ghost reduction and AF performance over its predecessor and adds a rugged dust- and moisture-resistant design. The lens has a ZEISS T* coating on its optical surfaces that minimizes ghosting and flare plus aspherical and ED (extra-low dispersion) glass elements that suppress aberration and minimize distortion. The new lens also features enhanced AF capabilities compared to the original 24-70mm F2.8 lens, delivering approximately 4x the subject tracking speed thanks to their SSM (Super Sonic wave Motor) system and faster, more powerful processing in the lens LSI.
