Pre-Photokina 2008: Alongside the A900 announcement, Sony has introduced two new high-end lenses to augment its full-frame lens range. The addition of the Carl Zeiss Series 16-35mm F2.8 and G Series 70-400 F4-5.6 means Sony now offers premium grade zooms all the way from 16mm to 400mm. The 16-35mm complements the recently introduced Carl Zeiss Series 24-70mm F2.8 and means F2.8 zooms are available from 16mm to 200mm. Both the new lenses feature customizable AF stop buttons that can operate the A900's 'Intelligent Preview' function.
