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.
Compact and lightweight for constant carrying and comfortable 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 5.8 oz (162 g). The lens is ideal for shooting scenery or snaps, or movie shooting with a gimbal, or selfie shooting using the wide angle of view. Mobility is delivered by the compact design that matches both full-frame and APS-C bodies.
High corner-to-corner image quality from state-of-the-art optics
High image quality is realized by state-of-the-art optics using three aspherical elements, delivering high resolution 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.
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 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.
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.
High operability and reliability in a compact design
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.
