Sigma's dedicated 1:1 macro for DSLR mounts — sharp at macro distances with smooth manual focus.
The Sigma 105mm f/2.8 EX Macro is a true 1:1 life-size macro lens available for multiple DSLR mount systems. Part of Sigma's EX professional line, it provides a working distance of approximately 31cm at maximum magnification, suitable for insects and product photography.
Optically excellent at macro distances — sharp across the frame with well-controlled aberrations. At portrait distances it delivers pleasant rendering with smooth bokeh. Autofocus is HSM in later versions, providing quiet operation. Manual focus ring is well-damped for precise macro work.
Available in Canon EF, Nikon F, and Sony A mounts. 58mm filter thread. Approximately 460g. No stabilisation. Full-frame coverage. Internal focus design — barrel length stays constant. EX designation indicates Sigma's professional tier with metal barrel construction.
Common used and good value — a respected macro lens. Multiple versions exist — later ones have HSM AF motors. Check for smooth focus ring operation and clear optics. The Sigma 105mm f/2.8 DG OS HSM Macro is the significantly improved successor with stabilisation.
