The Sony FE 40mm f/2.5 G is a compact, high-performance prime lens designed for Sony E-mount mirrorless cameras. Combining a versatile wide-normal focal length with advanced G Series optics and a lightweight construction, this lens is an excellent choice for street photography, portraits, travel, landscapes, and everyday shooting. Its portable design and intuitive controls make it particularly appealing to photographers and videographers seeking professional image quality without the bulk of larger lenses.
Designed for full-frame Sony E-mount cameras, the 40mm focal length provides a natural perspective that works well across a variety of photographic applications. When mounted on a compatible APS-C camera, it offers an approximately 60mm equivalent focal length, making it particularly useful for portraits and detailed compositions. The bright f/2.5 maximum aperture provides flexibility in challenging lighting conditions while allowing for effective control over depth of field.
The advanced optical construction incorporates three aspherical elements designed to minimize spherical aberrations and distortion while maintaining excellent sharpness and clarity throughout the image frame. Sony’s G Series optical design delivers accurate color reproduction, high contrast, and consistent image quality. A rounded seven-blade diaphragm contributes to smooth, natural-looking background blur when photographing subjects with selective focus techniques.
Two linear autofocus motors provide fast, accurate, and quiet focusing performance, making the lens suitable for both still photography and video recording. The internal focusing mechanism maintains a consistent lens length during operation, while Linear Response manual focusing offers precise and predictable control when making manual focus adjustments.
The lens features a dedicated aperture ring with a selectable click/de-click mechanism, allowing photographers to make tactile aperture adjustments while providing smooth, silent transitions for video applications. An AF/MF switch and customizable focus hold button offer additional convenience, allowing quick access to frequently used focusing functions directly from the lens barrel.
Close-focusing capabilities further enhance the lens’s versatility, with a minimum focusing distance of approximately 9.8 inches in manual focus mode and 11 inches when using autofocus. A maximum magnification of 0.23x in manual focus mode allows photographers to capture detailed close-up images of smaller subjects.
Constructed with a durable aluminum exterior, the FE 40mm f/2.5 G features a compact profile measuring approximately 1.8 inches in length and weighing just 6.1 ounces. Its dust- and moisture-resistant design provides additional protection when working in challenging environments, while a fluorine coating on the front element helps resist fingerprints, moisture, and debris for easier cleaning.
Combining professional optical performance, responsive autofocus, and a lightweight, portable design, the Sony FE 40mm f/2.5 G is a versatile prime lens for photographers and filmmakers seeking excellent image quality and convenient everyday handling.
