Sigma's long macro prime — 180mm f/3.5 with 1:1 magnification and excellent working distance.
The Sigma 180mm f/3.5 EX APO DG IF Macro HSM is a long telephoto macro providing true 1:1 magnification at 180mm — one of the longest macro focal lengths available. The extended working distance at maximum magnification is ideal for insect and nature photography.
Optically very good — sharp at macro distances with APO correction for chromatic aberration control. The 180mm focal length provides approximately 46cm of working distance at 1:1 — much more than 100-105mm macros. HSM motor for fast, quiet AF. IF internal focusing.
Nikon F mount with 72mm filter thread. Approximately 975g — heavy for a macro but expected for 180mm. No stabilisation. Full-frame coverage. Tripod collar included — needed at this weight. EX professional build quality.
Available used at mid-range prices. The long working distance is the unique selling point — ideal for skittish insects and reptiles. The weight requires a tripod for best results. Later versions improved with OS stabilisation. For macro photographers who need maximum working distance.
