Sigma 105mm f/2.8 MACRO

The Sigma 105mm f/2.8 EX DG OS Macro is a professional large aperture medium telephoto macro lens that offers advanced performance for close-up photography applications. This lens excels in macro work with a true 1:1 magnification ratio, allowing photographers to capture subjects at life-size reproduction on the sensor. Sigma's proprietary OS (Optical Stabilizer) system enables confident handheld close-up photography by providing effective image stabilization. The optical design incorporates 11 elements in 16 groups, including Special Low Dispersion (SLD) and high refractive index SLD glass elements that provide excellent correction for all types of aberrations and distortions. The innovative floating focusing system moves two different lens groups to different positions in the optical path, compensating for astigmatic and spherical aberrations while maintaining extremely high optical performance from infinity to 1:1 macro distances. The Super Multi-Layer Coating reduces flare and ghosting, ensuring high contrast images in various lighting conditions. The Hyper Sonic Motor (HSM) ensures quiet, high-speed autofocus operation with full-time manual focus capability. The lens features a rounded 9-blade diaphragm that creates attractive blur in out-of-focus areas, making it suitable for both macro and portrait photography. With dimensions of 70x98mm and weighing 726g, it provides professional performance while remaining manageable for extended shooting sessions.
