Ideal For Portrait And Astro Photographies

By incorporating 17 optical elements in 12 groups—an uncommonly large number of elements for a prime lens. the optical system minimizes axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume through the inclusion of three FLD glass elements, two SLD glass elements, and one aspherical lens element. The area in focus is extremely sharp, while the area out of focus features a beautiful bokeh effect with highly natural colors, making this lens a powerful choice for portrait photography. The optical system also minimizes sagittal coma flare, making this lens excellent for capturing starry skies.

Compatible With Full-Frame Sony E-Mount Cameras

SIGMA MOUNT CONVERTER MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not addressed by MOUNT CONVERTER MC-11.
