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.

Designed To Minimize Flare And Ghosting

SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
