About this item:

Nimble Wide-Angle
Satisfy your wide-angle fix on your full-frame E-mount camera with the fast and compact FE 28mm f/2 Lens from Sony. It boasts a bright design, advanced optics, and a sleek stature that makes it a great option for walkaround, everyday shooting, including street, architecture, and travel subjects.
Optics:
Two extra-low dispersion glass elements are featured in the lens design to help reduce chromatic aberrations and color fringing for improved clarity and color neutrality.
Three aspherical elements, including one Advanced Aspherical (AA) element, are incorporated in the lens design to reduce astigmatism, field curvature, coma, and other monochromatic aberrations.
Bright f/2 maximum aperture provides the ability to create images with a shallow depth of field as well as work in low-light conditions.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.
Autofocus and Design
Linear autofocus motor and internal focus design provide quick and precise autofocus performance and enables accurate and silent focusing while recording videos.
Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.
If looking for an even wider perspective, this 28mm can accept optional Ultra-Wide and Fisheye Conversion Lenses, which will transform the lens into a 21mm or 16mm lens, respectively.
