The high-quality G Lens optical design incorporates three aspherical lens elements for sharp detail and outstanding corner-to-corner resolution. In addition, the state-of-the-art optical design takes maximum advantage of the short flange back, unique to mirrorless cameras, to realize stunning compactness at 68mm diameter x 45mm and a weight of only 173g. 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.

Beautiful Natural Bokeh

The f/2.5 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.

Corner-to-Corner Sharpness

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.

7-Blade Circular Aperture

While conventional aperture blades have flat sides that create unappealing, polygonal-shaped defocused points of light, the FE 40mm f/2.5 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. 

Two Linear Motors for Fast, Precise Autofocus Tracking

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 f/2.5 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 that require tracking a moving subject.

Natural, Linear Manual Focus Response

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.

Close-Ups in a Standard Field of View

Get a unique perspective through close-up, wide-angle shooting. The standard 40mm angle of view is useful in applications from snapshots to movie shooting. The FE 40mm f/2.5 G features an impressive minimum focus distance of 11.02-Inch (0.28m) (AF) / 9.84-inch (0.25m) (MF) and maximum magnification of 0.2x (AF) / 0.24x (MF). With the wide f/2.5 max. aperture, you can also shoot close-ups with beautiful blurred background bokeh.

Built for Both Worlds: Ideal for Still and Video Creators

The FE 40mm f/2.5 G lens has clear advantages for moviemaking. With a wide 40mm angle of view on full-frame bodies and 60mm on APS-C bodies or Super 35mm cameras, dual linear motors for fast, precise autofocus and tracking, a bright f/2.5 maximum aperture for beautifully defocused background bokeh, excellent close-up performance and a class-leading ultra-compact and lightweight design, this lens is ideal for all types of content creators. In addition to the super small size and lightweight, its internal focus design makes it convenient for use on compact gimbals or grips for vlogging and other applications.
