Sony FE 28-60mm f/4-5.6 Overview Impressively compact and versatile, the Sony FE 28-60mm f/4-5.6 is a wide-angle to long-normal zoom characterized by its retractable design and sleek profile. The svelte design makes this lens ideal for walkaround, everyday shooting, and the flexible focal length range benefits a wide range of subject types. The optical design incorporates three aspherical elements, which help to reduce distortion and spherical aberrations and promote greater sharpness and accurate rendering. Complementing the optics is a linear motor and internal focusing design, which achieve quick and quiet autofocus performance for both photo and video needs. The lens body is also weather-sealed to permit working in trying environmental conditions. Compact zoom is designed for full-frame Sony E-mount mirrorless cameras but can also be used with APS-C models where it provides a 42-90mm equivalent focal length range. Retractable design maintains an especially compact profile when not in use. Three aspherical elements help to reduce spherical aberrations and distortion throughout the zoom range for improved sharpness and accurate rendering. Linear motor, along with an internal focusing mechanism, promotes fast, precise, and quiet focusing performance to suit both stills and video applications. Dust- and moisture-resistant design suits working in inclement weather conditions. Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
