• Compact and lightweight at only 6.2 oz.

• Excellent G Lens sharpness and contrast

📸 A Natural Everyday Perspective

The 40mm focal length sits comfortably between the environmental view of a 35mm lens and the tighter perspective of a 50mm.

It is wide enough for street scenes, travel, and documentary photography while remaining natural and flattering for portraits, food, products, and family moments. This balance makes it a strong choice for photographers who want to carry only one prime lens.

🪶 Compact Enough to Go Anywhere

At approximately 6.2 oz. and only 1.8 inches long, the FE 40mm F2.5 G creates an exceptionally portable full-frame setup.

It balances naturally on compact a7C-series cameras but is equally useful on larger professional Alpha bodies when minimal size and weight are priorities.

🔍 Premium G Lens Image Quality

Three aspherical elements help control distortion and spherical aberration while maintaining strong resolution across the frame. Sony’s optical coatings reduce flare and ghosting for clear, high-contrast images in difficult lighting.

A seven-blade circular aperture produces pleasing background blur and clean out-of-focus highlights when the lens is used near its maximum aperture.

⚡ Fast, Quiet Autofocus

Two Linear Motors provide quick, accurate, and quiet autofocus for still photography and video. The lens works seamlessly with Sony’s face, eye, and subject-recognition autofocus systems.

Its internal focusing design maintains the lens’s compact dimensions and provides responsive performance for street photography, children, pets, and other moving subjects.

🎥 Professional Controls in a Tiny Lens

Despite its small size, the lens includes many of the physical controls found on larger professional Sony optics:

• Physical aperture ring

• Selectable aperture click switch

• Customizable focus-hold button

• AF/MF switch

• Linear Response manual focus

• Quiet internal autofocus

The aperture ring can provide traditional tactile clicks for photography or smooth, quiet adjustment for video.

🔎 Close-Focusing Versatility

The lens focuses as close as approximately 11 inches with autofocus and 9.8 inches with manual focus.

Maximum magnification reaches approximately 0.20x with autofocus and 0.23x with manual focus, making the lens useful for food, products, flowers, wedding details, and everyday close-ups.

📸 Who Is This Lens For?

The Sony FE 40mm F2.5 G is an excellent choice for:

• Street and documentary photographers

• Travelers wanting a lightweight prime

• Family and everyday photographers

• Environmental portrait photographers

• Food and lifestyle creators

• Filmmakers using compact rigs or gimbals

• Anyone wanting one small, natural-perspective lens

⚖️ How It Compares

Compared with the Sony Sonnar T FE 35mm F2.8 ZA*, the 40mm G offers a slightly tighter perspective, a brighter aperture, closer focusing, and more extensive physical controls. The 35mm ZA is marginally wider, lighter, and slimmer.

Compared with the Sony FE 50mm F1.8, the 40mm G provides faster autofocus, wider coverage, closer focusing, and premium construction. The 50mm F1.8 offers a brighter aperture and stronger background separation at a lower price.

ℹ️ Full-Frame and APS-C Compatibility

On a full-frame Sony camera, the lens provides its native 40mm perspective. On an APS-C camera such as the a6700 or a6400, it provides an angle of view equivalent to approximately 60mm, making it useful for portraits, details, and everyday photography.

The lens does not include Optical SteadyShot but works with in-body stabilization in compatible Sony cameras.
