Sigma has just announced a mirrorless version of their 60-600mm f/4.5-6.3 DG DN OS Zoom Lens compatible with full-frame E and L-Mount cameras. It is the first interchangeable lens to bring 10x magnification to the mirrorless form factor. Both stabilization and autofocus have been revamped for the 60-600mm. A new optical stabilization algorithm (OS2) provides 6–7 stops of stability, depending on the focal length, to allow sharp image capture even when handheld on the long end of the lens. A newly developed High-response Linear Actuator (HLA) motor delivers fast and quiet AF capable of keeping pace with quick-moving subjects. A focus limiter switch on the side of the lens barrel helps speed up subject recognition whether you’re using AF or manual focusing, and dual Action Zoom allows rotary and straight zooming actions. On-lens control also includes three customizable AFL buttons for AF/MF switch, zoom lock switch, and OS switch. The SIGMA 60-600mm F4.5-6.3 DG DN OS will be offered for an MSRP of $1,999US through authorized SIGMA America retailers, and will be available beginning mid-February, 2023.  To learn more visit:  https://www.sigmaphoto.com/60-600mm-f45-63-dg-dn-os-s
