An innovative optical design that includes three aspherical elements effectively corrects field curvature and aberration, achieving outstanding resolution throughout the lens’s wide 15 mm field of view, even at full F1.4 aperture. One ED (Extra-low Dispersion) glass element and one Super ED glass element further suppress chromatic aberration and effectively reduce peripheral color fringing.

 

This lens’s large F1.4 aperture makes it possible to produce beautiful bokeh that is enhanced by precisely controlled spherical aberration and a 7-blade circular aperture. 0.17 meter minimum focus and 0.15x maximum magnification¹ let you get close to the subject while producing deep background bokeh. Impressive close-up capability is an advantage for movies as well as stills.

The small size and low weight of this lens make it a perfect match for compact APS-C cameras. A design that maximizes the benefits of aspherical elements and the short mirrorless flange back distance delivers stunning performance in a lens that is only 2-5/8 x 2- 3/4" (66.6 x 69.5mm) and weighs only 7.8 oz. (219 g). A great choice for wide-angle landscapes, architecture, interiors, and snapshots in general.

 

Two linear motors give this large-aperture lens impressively fast, precise autofocus and tracking performance for both stills and movies. AF and tracking are so responsive that the full speed potential of the camera used can be fully realized so that even fast or erratically moving subjects can be reliably captured.

The focus ring features Linear Response MF for direct manual focusing that responds like mechanical focus. There is also an aperture ring with an click stop on/off switch for intuitive aperture control, a focus hold button and focus mode switch for extra focus control versatility. And to ensure maximum reliability in challenging outdoor conditions, this rugged lens has a dust and moisture resistant design.³
