A classic wide normal focal length prime lens, the FE 40mm f/2.5 G from Sony is characterized by its ultra-compact form factor. The versatile focal length suits shooting everything from street to landscapes, portraiture, and documentary subjects, and it features an advanced optical design for well-corrected imagery with a high degree of sharpness and clarity. Additionally, the ultra-compact form factor makes it effortless to have handy at any time.
The lens design includes an extra-low dispersion and aspherical elements to reduce a variety of aberrations, color fringing, and distortion. The optics are complemented by a Nano AR II coating 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. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions.
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.
This 40mm lens is designed for full-frame Sony E-mount mirrorless cameras; however, it can also be used with APS-C models where it provides a 60mm equivalent focal length.
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, provides 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.
A focus hold button is featured on the lens barrel for intuitive tactile control and rapid access to select settings.
Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
Rounded 7-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
