Versatile Ultra Wide-Angle Zoom:
Designed for Sony E-mount APS-C-format mirrorless cameras, providing a 35mm equivalent focal length range of 16.5-30mm.
Bright and Constant f/2.8 Aperture:
Features a fast and constant f/2.8 maximum aperture, ensuring consistent brightness throughout the zoom range. This aperture setting allows for improved control over depth of field and enhanced low-light performance.
Optical Design:
Incorporates advanced optical elements, including one XLD (eXtra Low Dispersion) element, two LD (Low Dispersion) elements, and two glass-molded aspherical elements.
These elements work together to minimize chromatic aberrations, color fringing, and image distortion, resulting in improved clarity and color accuracy.
BBAR-G2 Coating:
Utilizes the BBAR-G2 (Broad-Band Anti-Reflection) Coating on lens elements to suppress internal reflections, flare, and ghosting. This coating enhances contrast and color fidelity, especially in challenging lighting conditions.
RXD Autofocus Motor:
Equipped with an RXD (Rapid eXtra-silent stepping Drive) autofocus motor, providing quiet, quick, and smooth focusing performance. This makes the lens suitable for both still photography and video applications.
Ultra Close Focusing:
Offers a minimum focusing distance of 5.9″ at 11mm, allowing for dynamic wide-angle macro imaging. This feature makes close objects appear larger and distant objects smaller. The f/2.8 aperture also produces a shallow depth of field with soft bokeh background details.
Weather-Sealed Construction:
Designed with moisture-resistant construction, making it suitable for use in inclement weather conditions.
Features a fluorine coating on the front lens element, providing protection against dust, dirt, and smearing.
Rounded Diaphragm:
Utilizes a rounded seven-blade diaphragm, contributing to a pleasing bokeh quality in out-of-focus areas.
