Sony FE 40mm f / 2.5 G Lens - SEL40F25G.SYX
A classic wide normal focal length prime lens, Sony's FE 40mm f / 2.5G is characterized by its ultra-compact form factor. The versatile focal length is suited to shooting everything from streets to landscapes, portraits and documentary subjects, and features advanced optical design for well-corrected images with a high degree of sharpness and clarity. Plus, the ultra-compact form factor makes it easy to have on hand at any time.
The lens design includes extra-low dispersion and aspherical elements to reduce a variety of aberrations, color fringes, and distortion. The optics are complemented by a Nano AR II coating that also suppresses flare and ghosting to improve contrast. Balancing the optics is an XD linear motor system that uses two separate focus motors to deliver particularly quiet, precise and fast autofocus performance. The lens also has a dust and moisture sealed design and a fluorine-coated front lens element to aid shooting in inclement conditions.
Designed to achieve remarkably high resolution and sharpness through correction for a wide variety of spherical and chromatic aberrations, this lens features a robust and intuitive to handle physical design that benefits both photography and film 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.
XA (Extreme 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 superior precision. accurate representation.
The extra low dispersion element is included in the lens design and helps reduce chromatic aberrations and color fringing to improve clarity and color neutrality.
Nano AR Coating II has been applied to reduce surface reflections, flare and ghosting to increase contrast and color reproduction in bright lighting conditions. This updated coating is more suitable for larger curved elements and is especially adept at minimizing internal reflections.
Two XD linear motors, coupled with an internal focusing design, provide fast, quiet, and accurate autofocus performance. This design also contributes to a more natural and 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 included on the lens barrel for intuitive touch control and quick access to selected settings.
The physical aperture ring can be clicked off for smooth and quiet aperture change for the benefit of video applications.
The sealed design against dust and moisture allows for better work in inclement conditions and the rubberized control rings benefit handling in colder temperatures.
The fluorine-coated front element resists dust, moisture and fingerprints and is easy to clean.
The rounded 7-blade diaphragm contributes to pleasant bokeh quality when using selective focus techniques.
