The 24-105mm F4 is a very versatile focal range and a simple everyday lens. With the increasing resolution capabilities of new sensors, it is designed to highlight the true potential of evolving camera technology. Sigma's 24-105mm F4 features proprietary Sigma technology, including our Hyper Sonic Motor (HSM), which ensures fast, quiet, and precise autofocus, as well as our Optical Stabilizer (OS), which compensates for camera shake. A rounded diaphragm with 9 blades creates beautiful background blur, while FLD and SLD glass elements correct various aberrations, distortions, and curvatures. The use of thermally composite materials (TSC) reduces size and weight and is compatible with the Sigma USB Dock for further customization and the new Mount Conversion Service as part of the new Global Vision design.
