Rounded Diaphragm with 13 Blades: The lens incorporates SIGMA's first 13-blade diaphragm, which maintains a circular shape even when stopped down from the maximum aperture Minimizes Focus Breathing: Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. The change in angle of view due to focus shift is minimized, creating a natural-looking focus shift Minimizes Flare and Ghosting: Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology Lightest Weight Lens Body: By uncompromisingly pursuing high optical performance and portability, which are inherently contradictory, the highest level of performance has been condensed into the lightest lens body in its class Capture moments in stunning detail!!!
