High image quality is realized by state-of-the-art optics using three aspherical elements and one ED (Extra-low Dispersion) glass element, delivering high resolution and suppressing color fringing in all parts of the image. The aspherical 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. The ED glass element suppresses chromatic aberration and effectively reduces color fringing that is more likely to occur in the image periphery.

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, 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.

Despite its compact size, the lens provides a focus hold button, focus mode switch, aperture ring, aperture click switch, and Linear Response MF for intuitive operability and comfortable shooting. 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-resistant², providing reliability in harsh outdoor shooting environments.
