Ultra wide-angle zoom designed for full-frame E-mount mirrorless cameras, this lens is also compatible with APS-C models where it provides an 18-36mm equivalent focal length range.
Constant f/4 maximum aperture offers consistent performance throughout the zoom range.
Four aspherical elements are featured in the optical design to control spherical aberrations in order to produce a high degree of sharpness while also limiting distortion.
One Super ED and three ED elements are used to suppress chromatic aberrations and color fringing for improved clarity and color accuracy.
A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.
A Direct Drive Super Sonic wave Motor AF system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control.
A dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
