Wide-Normal Portable Prime
A comfortable focal length with an especially portable design, the Sony FE 40mm f/2.5 G is a versatile prime; an ideal single focal length option for a broad variety of situations. This lens's smart build and sophisticated G Series optics mix with intuitive handling and the sleek form factor to make it a go-to option for anything from street to landscape to travel applications.
Matched Set of Compact Primes
Together with the FE 24mm f/2.8 and 50mm f/2.5 G lenses, these three lenses form a cohesive trio with similar styling, image quality, and ergonomics:
  • All lenses prioritize a compact profile with an emphasis on intuitive handling; each features a manual aperture ring along with other tactile controls.
  • The three lenses share the same 49mm filter ring diameter.
  • Matched aluminum finish with stylish focal length and aperture engravings, both aperture and focusing rings, and matching metal lens hoods.
G Lens Series
  • Three aspherical elements promote more uniform sharpness across the frame by suppressing spherical aberrations and distortions.
  • Rounded 7-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Focus Control for Stills and Video
  • Two linear motors deliver quick and accurate autofocus performance, along with capable subject tracking for working with fast-moving subjects. This AF system is also especially quiet to suit its use for cine applications.
  • Internal focusing design limits the overall length of the lens for faster, more responsive focusing.
  • Linear Response manual focus control offers more natural handling and an AF/MF switch is located on the lens barrel for tactile control over this setting.
  • Customizable focus hold buttons are present on the lens barrel for intuitive tactile control and rapid access to select settings.
  • Impressive close-up performance for working with close-up subjects; this lens has a minimum focusing distance of 9.8" with MF (11" with AF), which results in a 0.23x maximum magnification.
Sleek-but-Robust Design
  • Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
  • Lens measures 1.8" and weighs 6.1 oz, making it a great portable choice that's well-suited to both full-frame and APS-C bodies.
  • Dust- and moisture-sealed design better permits working in inclement conditions.
  • Fluorine-coated front element is easy to clean and resists dust, moisture, and fingerprints.

Ideal Lens

Took this lens to Paris on my Sony a7c what a combo for the street, cityscape and anything I need it for. Portraits, landscapes, street, the perfect lens and so user friendly and optically terrifi

Terrific weight, size, quality

Really, it is sharp. Mostly I'm using it at f5.6 to 11 but landscapes and interior view at 2.5 were excellent. Color is fine. Focus hold works. Yeah, I wish it had been cheaper, but it will allow me to travel almost comfortably with my Sony A7R3 around my neck rather than my lovely lightweight Fuji XE2. Attached photos are all jpegs processed and sharpened in LrC. I highly recommend it based on quality alone. Its low weight is a major benefit and the low profile makes it even more mobile. I only shoot stills, so I can't comment on video.

Amazingly light and sharp little lens! great for walk around or small outings where you don't want to bring a chunky lens.

Perfect mate for Any a7C

This is a surprisingly good lens, considering its small size and weight. I like the imagery, color, and contrast. It focuses fast and accurately, is well-built, and has useful buttons, switches. I also like the aperture ring with a click/de-click button (!) plus the AF/MF switch, as well. It pairs perfectly with the a7C, creating a very light, versatile, easy to carry around kit. I have a feeling it will also find it's way onto my A7IV.

Great balance of size and quality

This has rapidly become my default lens, and then I'll switch to a different lens if the situation calls for it. Image quality has been great, autofocus has been great. The only real complaint I have with this lens is that sometimes I want more bokeh, but it really has plenty for most situations. If you need maximum bokeh, you're probably going to be using a noticeably heavier lens. In addition to the typical uses, I think the extra field of view from the 40mm lens (compared to the 50mm f/2.5) is perfect if you plan to occasionally use your camera for video conferencing with it mounted to the back of your desk.

Needed a walk-around lens

This lens really fits a need. I use mostly primes, including a Batis 25/2 which I love. I am excited to bring this back out when the weather gets nicer. I wish it was a bit wider like 35. It is sharp and solid

Perfect for street photography

I bought this for everyday use in addition to the 35mm f/1.4 GM and the 24mm f/2.8 lens, this one's sibling. Small, lightweight, great image quality, and solid build makes this a great option and complements my set up as this one covers everyday use, during commute, while the 35mm is perfect for weekend usage or outings dedicated to photoshoot. The image quality is almost as good as the 35mm f/1.4 GM-straight out of the body RAW lacks the high micro-contrast that 35mm creates, but can be easily compensated in LightRoom and the resulting image is as satisfactory as that from the 35. I would recommend this lens for anyone who is looking for a small lightweight lens to everyday use in street photography.

Small, light, feels well built. Sharp at all apertures. Good tactile feedback on the aperture ring. Would recommend to a friend.

What is the purpose of the aperture index mark on the aperture ring?
Asked by: Mark
That allows you to easily see what aperture you are in without having to look at the camera. Some people like the old school dials like that since they do not have to keep looking at the camera LCD to see what aperture they are on.

Is lack of OSS a problem for video work? I have the A7RIV and want a compact travel lens for hand-held video and photography. I like the AF/MF features a lot, but lack of OSS is a concern.
Asked by: Chris
The lack of Optical Steady Shot in the FE 40mm f/2.5 G Lens would not be a problem since the A7R IV would already have stabilization built in.

Do focus ring and aperture control ring work without lens communication? Since they are built onto the lens is it possible to adapt it onto other camera bodies via adapters that don't have lens communication? For instance, l mount bodies.

This lens offers control of the aperture via the camera when setting the aperture ring to A or manual control directly on the ring. This is available on Sony E mount bodies only.

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.

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
