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.
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.
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.
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 holds the camera can remain fixed while the left thumb operates Eye AF, for more stable holding.
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.
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 focus/autofocus switching
The "focus mode switch" supports comfortable shooting by enabling instant switching between AF and MF depending on shooting conditions.
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.
Sharp, compact, lightweight, beautiful design
venusfotografo, Costa Rica:
Extremely sharp wide open, the center is already optimal from f/2.5 and the corners barely improve from stopping down. It is weightless when mounted on a camera, the ligthest lens i've known. The build quality it top notch, the focus ring is like using a real manual focus lens and the aperture ring is very satisfying and useful. AF is extremely fast and silent. Very happy overall!

Mobility is a key feature, preserving the compactness of the overall E-mount system whether shooting with a full-frame or APS-C body or shooting either still images or movie.
The F2.5 max aperture is ideal for low-light situations for maximum light gathering capability while also providing a shallow depth of field. Beautiful natural bokeh expected from a G Lens is delivered with minimal spherical aberration and provision of a 7-blade circular aperture for round defocused light sources.
High image quality is realized by the inclusion of three aspherical lens elements compensate for various aberrations, delivering high resolution performance from corner to corner of the image, even from the widest aperture with shallow depth of field.
While conventional aperture blades have flat sides that create unappealing, polygonal-shaped defocused points of light, the FE 40mm F2.5 G incorporates a 7-blade circular aperture mechanism to maximizes the beauty of this large-aperture prime-lens. The wide f2.5 aperture and circular aperture blades contribute to impressive images in which the subject stands out against a smoothly defocused foreground and background, as well as perfectly round points of defocused light.
Taking full advantage of the continuing rapid advances in the speed and performance of newer camera bodies, two linear motors are used in the FE 40mm F2.5 G lens to deliver fast, precise AF (autofocus) with excellent tracking performance. Tracking is maintained despite instantaneous changes in subject motion, making the lens ideal for situations require tracking a moving subject.
Linear Response MF (manual focus) ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise in both still and movie modes.
Get a unique perspective through close-up, wide angle shooting. The standard 40mm angle of view is useful in applications from snap shots to movie shooting. The FE 40mm F2.5 G features an impressive minimum focus distance of 11.02” (0.28m) (AF) / 9.84” (0.25m) (MF) and maximum magnification of 0.2x (AF) / 0.24x (MF). With the wide F2.5 max. aperture, you can also shoot close-ups with beautiful blurred background bokeh.
