Zoom Lenses The advent of the digital age-both in terms of photography itself and the tools used for optical design-has made highperformance zoom lenses more accessible and easier to use than ever before. Not only are zoom lenses a great way to be ready for any photo opportunity, but the freedom to rapidly change framing and composition without having to change the camera position offers creative flexibility that is just too appealing to ignore. In many situations, that speed and freedom can be the key to grabbing shots that would otherwise be missed. Advanced Sony design and manufacturing technology delivers outstanding image quality with unparalleled zoom versatility and convenience.

City scenes, crowded markets, historical ruins... all of these are subjects that can benefit from the wide perspectives this lens provides. It's also a great lens for shooting dynamic images with deep perspective. Although wide angles present more opportunities for image-degrading lens flare, the SAL1118 features special elements and design that reduce flare and aberrations to a minimum for crisp, high-contrast images even under difficult conditions. • Weight (approx): 360 g • Dimensions (Dia. x L): 83 x 80.5 mm • Max. magnification ratio: 0.125x 19
