This wide-angle, large aperture 15mm Aps-c prime offers dynamic perspectives, corner-to-corner sharpness, naturally rendered bokeh in an incredibly mobile package. Fast, precise, quiet Af, optical design for refined movies shooting and rugged reliability make it ideal for use with Aps-c and Super35 cameras for both still and video content creators.Spectacular rendering and bokeh in a wide-angle F1.4 G LensWith stunning G Lens rendering and expressive F1.4 bokeh, this 15 mm (35mm full-frame eq: 22.5 mm) wide-angle prime lens for Aps-c and Super35 cameras can deliver dynamic perspectives and expression. Whether you're shooting stills or movies, superb operability and Af performance combine with compact, lightweight mobility and multi-faceted versatility.Eye-opening G Lens resolution and contrast from full apertureAn innovative optical design that includes three aspherical elements corrects field curvature and aberration for outstanding resolution through 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.Breathtaking, naturally rendered bokeh at wide F1.4 apertureThis 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. Minimum focus distance of just 6.7"" (0.17 m) and 0.15x maximum magnification 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.Compact and lightweight for extraordinary shooting freedomThe small size and low weight of the lens makes it a perfect match for compact Aps-c as well as Super35 E-mount cameras. A design that maximizes the benefits of aspherical elements and the short mirrorless flange back distance delivers stunning optical performance in an Aps-c format lens that is only 2-5/8 x 2-3/4"" (66.6 x 69.5 mm) and weighs only 7.8 oz. (219 g). A great choice for wide-angle landscapes, architecture, interiors and snapshots in general.Advanced autofocus maximizes the camera's speed potentialTwo 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 in use can be utilized so that even fast or erratically moving subjects can be reliably captured.Manual aperture ring w/ selectable on/off click for stills or movieAn aperture ring provides intuitive control plus the fast response required for professional applications. It also includes a switch that turns the aperture click stops on or off - On for tactile feedback when shooting stills or Off for seamless, silent control when shooting movies.Advanced optics for refined movies with minimal breathingState-of-the-art lens technology packed into this remarkable large-aperture wide-angle lens reduces unwanted focus breathing and angle of view shifts when focusing. It also supports the breathing compensation function in compatible alpha cameras, further reducing unwanted angle of view shifts during focusing for smooth, high-quality movie footage.Consistent balance and center of gravity for easy handlingThanks to a refined internal focus mechanism, the lens's length remains constant while focusing for ideal balance and handling.
