The versatile focal length suits shooting everything from street to landscapes, portraiture, and documentary subjects, and it features an advanced optical design for well-corrected imagery with a high degree of sharpness and clarity. Additionally, the ultra-compact form factor makes it effortless to have handy at any time.
The lens design includes an extra-low dispersion and aspherical elements to reduce a variety of aberrations, color fringing, and distortion. The optics are complemented by a Nano AR II coating that also suppresses flare and ghosting for improved contrast. Balancing the optics is an XD Linear Motor system that uses two separate focusing motors to deliver especially quiet, precise, and quick autofocus performance. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions.
