Sony E-Mount FE 40 MM F2.5 G Lens - SEL40F25G

Compact, superbly built standard prime lens

This standard prime lens packs the high image quality and beautiful bokeh of the G Lens into a compact design with superb build quality and intuitive operability. Easily carried anywhere and anytime, it’s ideal for snap-shooting both portraits and views around town. The fast, precise and quiet AF is ideal for shooting both stills and movies, ensuring capture of those vital moments.

A matching set of portable primes

This is one of our G Lens primes (sold separately), offering different focal lengths but the same external look, 49‑mm filter diameter, compact design and layout. They’re compact enough to carry all three, so you’re ready for great shots across a range of scenes and subjects, and the similar weight even makes gimbal rebalancing easy. 

Intuitive, metal design and clear optics

The metal (aluminum) finish of the lens body and hood, plus the engraved focal length and aperture markings, emphasize a superb build quality. The ultra-compact lightweight design, the high image quality of the G Lens, the aperture ring and Linear Response MF deliver intuitive operability that makes shooting a pleasure.

Light for constant carrying and shooting

The mechanical design takes maximum advantage of state-of-the-art optics with an effective layout of three aspherical lens elements and the short flange back unique to mirrorless cameras to realize stunning compactness and a weight of only 6.2 oz (173 g). The lens is ideal for shooting snaps around town, or movie shooting with a gimbal. Mobility is delivered by the compact design that matches both full-frame and APS-C bodies.

Beautiful natural bokeh

A 7-blade circular aperture is provided, with precise control of the spherical aberration that affects bokeh delivering the beautiful natural bokeh of the G Lens.

Double linear motors for fast, precise and quiet AF

Two linear motors deliver fast, precise AF with superb tracking performance that maximizes camera body performance to capture decisive moments in street snaps, expression changes in portraits and the like. The fast, precise and quiet AF with superb tracking performance is ideal for shooting movies as well as stills.

Excellent close-up performance

A minimum focus distance of 0.92 ft (28 cm) (AF) / 0.82 ft (25 cm) (MF) provides excellent close-up performance. The lens is useful in many situations, like shooting close-ups of flowers or small objects you find around town with a blurred background that makes the subject stand out.

Cap and filter can also fit on the hood

The diameter of the threaded hood is equal to the filter diameter of the lens (49 mm), allowing the same cap and filter to be attached to both the hood and the lens barrel for added convenience.

Metal finish and dust/moisture resistance

The metal (aluminum) exterior finish of the lens body and hood contributes to reliability through increased strength and durability. The design is also dust- and moisture-resistant, providing reliability in harsh outdoor shooting environments.

Customizable focus hold button

The focus hold button is customizable from the camera menu, and can be assigned a function that the user prefers. For example, if the Eye AF function that automatically tracks human eyes is assigned, the fingers of the right hand that hold the camera can remain fixed while the left thumb operates Eye AF, for more stable holding.

Natural, linear manual focus response

Linear Response MF provides a direct response to subtle focus ring adjustments when focusing manually. Ring rotation translates linearly to a corresponding change in focus like a mechanical control, directly reflecting the intent of the photographer and allowing delicate focus adjustments.

Switchable aperture-ring click stops

The aperture ring provides the immediacy of operation that professionals seek for still and movie shooting. Click stops can be switched ON for tactile feedback when shooting stills, or OFF to suppress the clicks when shooting movies, for smooth and natural aperture adjustments in combination with the quiet linear motors. This is ideal for situations requiring silence, like stage movie shooting.

Easy manual/auto focus switching

The “focus mode switch” supports comfortable shooting by enabling instant switching between AF and MF depending on shooting conditions.

Accepts a variety of filters

The diameter of the threaded hood is equal to the filter diameter of the lens (49 mm), allowing the same cap and filter to be attached to both the hood and the lens barrel.  Thanks to its internal focus, the front lens element does not rotate, allowing attachment of circular polarizing filters for landscapes, ND filters for movies, etc., giving the user extra creative control.

60‑mm equivalent on APS-C bodies

This lens also balances well on APS-C bodies, providing a wide-angle focal length of 60 mm (35‑mm full-frame format equivalent), useful for shooting a wide range of scenes from snapshots around town to portraits.

Internal focus for comfortable movie shooting

The internal focus design maintains the overall length of the lens constant when focusing, allowing easy movie shooting with a gimbal or grip attached.
