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 5.8 oz (162 g).

High image quality is realized by state-of-the-art optics using three aspherical elements and one ED glass element. The aspherical elements compensate for various aberration. The ED glass element suppresses chromatic aberration and effectively reduces color fringing.

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.

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

A minimum focus distance of 0.79 ft (24 cm) (AF)/0.59 ft (18 cm) (MF) provides excellent close-up performance. Close-up shooting lets the subject stand out against a blurred background. With a wide 24-mm angle of view, the lens is also ideal for selfie shooting with a gimbal or grip attached.

The lens provides a focus hold button, focus mode switch, aperture ring, aperture click switch and Linear Response MF. The aluminium exterior finish of the lens body and hood contributes to reliability through increased strength and durability. The design is also dust and moisture resistant.
