The Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Canon EF is a benchmark short-telephoto prime built for photographers who demand life-size 1:1 magnification and razor-sharp close-up results. Compatible with full-frame and APS-C Canon EF-mount cameras, it combines a bright f/2.8 maximum aperture with Sigma’s Optical Stabilizer (OS) technology, making it equally powerful for available-light portraits, product photography, and intricate macro work.
Optically, the lens features two Special Low Dispersion (SLD) elements that virtually eliminate chromatic aberration and color fringing, while the Super Multi-Layer Coating suppresses flare and ghosting even in demanding backlit conditions. The Hyper Sonic Motor (HSM) delivers fast, whisper-quiet autofocus with full-time manual override, and the rounded 9-blade diaphragm renders beautifully smooth, creamy bokeh to isolate your subjects with stunning clarity.
