The Sony E 18-200mm F3.5-6.3 OSS LE is a variable maximum aperture superzoom lens for the Sony E-mount, released by Sony on May 17, 2012. The lens was designed to better accommodate users of Sony's E-mount mirrorless cameras in weight and size. Build quality The lens features an all-plastic construction with rubber focus and zoom rings. The barrel of the lens telescopes outward from the main lens body as it's zoomed in from 18mm to 200mm. To combat zoom creep, the lens features a small zoom lock switch on the main lens barrel. Optics The lens features an entirely new optical formula. The Tamron 18-200mm F/3.5-6.3 Di III VC is "nearly identical". Compared to its predecessor (the Sony E 18-200mm F3.5-6.3 OSS), this lens is softer and suffers from greater chromatic aberration. However, distortion has been reduced in the new design. See also List of Sony E-mount lenses Sony E 18-200mm F3.5-6.3 OSS References Camera lenses introduced in 2012 18-200 Superzoom lenses
