Sony FE 40mm f/2.5 G Overview

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.

is there a chance a 35mm will ever be released in this line of small G lenses?
Asked by: Bozmund
I would predict no because 40mm is very similar in focal length to 35mm plus they already make this small 35mm: https://bhpho.to/3dGSLKh

So is this Sony's answer to the next iteration of RX1r iii? No need because you have the 7C with one of these?
Asked by: Jay
Great question and we will have to wait and see. I’ve used both generations of the RX1 and both time found myself wishing I had a little more focal length at times and others a wider AOV. Still the appeal of a fixed lens P/S goes back to the Nikon 28&35 Ti’s, the Contax T2 and the Yashica T4. Today we have the Zeiss ZX1, Leica Q2 and two monsters in the category the Fuji X100’s and Ricoh GR series. There is a draw by some for a fixed lens high end camera with minimal options. We’ll have to wait and see what Sony does. Personally I am thinking the A7C with the 40mil would be a perfect companion for my Leica CL and 40mm C Summicron.
