From Sony: Sony introduces quiet, quick new super-zoom lens
DT55-300mm F4.5-5.6 SAM telephoto zoom lens for A-mount cameras - From flattering portraits to wildlife and extreme sports, every subject can be covered with the new SAL55300 telephoto zoom lens from Sony.
Optimised for all α A-mount camera models with APS-C sensors, the compact, stylishly designed interchangeable lens brings the action closer at a competitive price for every photographer.
A versatile 5.5x magnification range covers focal lengths from 55mm to 300mm. At maximum zoom, this represents 450mm super-telephoto (as 35mm equivalent) with plenty of power to capture the grace of animals in the wild or nail-biting track-side action.
The whisper-quiet Smooth Autofocus Motor (SAM) makes an ideal partner for the high-speed AF tracking capabilities of cameras with Translucent Mirror Technology. Even when your subject’s moving swiftly, you’ll be rewarded by frame after frame of crisply-focused images and Full HD video.
The advanced optical design of the SAL55300 gets the best from the high pixel counts of today’s high-resolution image sensors. Featured on premium Sony G Lens models, an ED (Extra-Low Dispersion) glass element reduces colour aberrations for improved image quality at medium to long focal lengths. An impressive MTF (Modulation Transfer Function) performance assures flawless resolution of the finest details.
The new SAL55300 A-mount interchangeable lens for A-mount cameras by Sony is available from mid-September 2012.
