The silver E 55-210mm f/4.5-6.3 OSS E-Mount Lens from S0NY features extra-low dispersion glass, a broad zoom range and aluminum alloy construction. On an APS-C camera, this zoom lens has a 82.5-315mm focal length range, suitable for event photography and portraiture alike. Internal focusing and linear motor-driven AF system help create responsive yet quiet focus while minimizing mechanical noise. Additionally, a separate manual focusing ring capable of Direct Manual Focus allows seamless transitions from AF to manual focusing. Two extra-low dispersion elements, combined with S0NY's Optical SteadyShot (OSS) image stabilization, improve the overall quality of images captured at the telephoto end of the zoom range, especially while shooting in low-light conditions. OSS is capable of reducing the appearance of camera shake by up to four stops. An aspherical focusing lens located in the center of the optical path help to reduce aberrations throughout the zoom range as well as improve the AF response time of the lens.
