Body & Optical Design

Comprising a total of 21 lens elements organized into 15 groups, this lens features four FLD elements, three SLD elements, and two aspherical elements, which collectively enhance the reproduction of bright light points. This configuration ensures exceptional sharpness throughout the entire viewing angle. The inclusion of two rear sheet filter slots and an Arca-Swiss compatible tripod collar facilitates long exposure photography, particularly beneficial for astrophotography. Furthermore, the lens is engineered to manage various lighting conditions, exhibiting high resistance to backlighting, thereby ensuring consistent clarity, sharpness, and superior image quality. Its robust construction is both dust- and splash-proof, complemented by a water- and oil-repellent lens coating, allowing it to endure challenging environmental conditions.

HLA Autofocus System

The High-response Linear Actuator (HLA) focusing motor brings remarkable speed, accuracy, and quiet operation to the Sigma autofocus system. For videographers, the optical design significantly reduces focus breathing. Additionally, the HLA enhances focus tracking capabilities for sports photography and other dynamic subjects, including cars, aircraft, and birds in flight, thereby ensuring that critical moments are captured without delay.
