The FE 50mm f/2.5 G Lens from Sony is characterized by its ultra-compact form factor. The versatile focal length suits shooting everything from street, portraiture, and documentary subjects, and it features an advanced optical design for well-corrected imagery with a high degree of sharpness and clarity. The optics are complemented by multicoating that also suppresses flare and ghosting for improved contrast. Balancing the optics is an XD Linear Motor system that uses two separate focusing motors to deliver especially quiet, precise, and quick autofocus performance. Designed to achieve notably high resolution and sharpness through the correction of a wide variety of spherical and chromatic aberrations, this lens features a robust and intuitive-to-handle physical design to benefit both photography and cine applications. Aspherical elements are incorporated into the optical design and feature superior surface precision for effective control over astigmatism, field curvature, coma, distortion, and other spherical aberrations for a high degree of sharpness and accurate rendering. Two XD Linear Motors, along with an internal focusing design, provide quick, quiet, and precise autofocus performance. This design also contributes to more natural, intuitive Linear Response manual focus control, and an AF/MF switch is located on the lens barrel for tactile control over this setting. Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
