Early this morning Sony launched an all new Telephoto Zoom lens, the DT 55-300mm F4.5-5.6 SAM (Model SAL55300). This affordable lens sports an appealing price tag of just $300 USD, however it still offers high-quality features and build materials. These include Sony’s Smooth Autofocus Motor (SAM) for “whisper-quiet” AF during still and video capture and ED (Extra-Low Dispersion) glass for improved image quality with less aberrations. The lens is designed specifically for use with APS-C cameras. The SAL55300 will be available sometime in September, 2012. For more details, read the press release below. Note: At the time of this post, Sony’s USA website was not showing the SAL55300 under their A-mount lens offerings.
