- ensuring the colour is perfectly reproduced on every shot. Able to achieve optical performance from infinity to 1:1 macro, a floating inner focusing system compensates for distortion & astigmatism. For convenient handling when you're out on a shoot, the length of Sigma's Macro Lens doesn't change length when you're focusing. Optical stabilisation Offering effective correction of four steps, the Sigma 180 mm f/2.8 APO EX DSG HSM Macro Lens is the first 180 mm optically stabilized telephoto macro lens in the world. Allowing you to emphasise your subject, the Sigma 180 mm Macro Lens has a maximum aperture of f/2.8, providing a bright viewfinder image. Super Multi-Layer Coating is used to reduce flare & ghosting. Combined with an optical design engineered to be resistant to strong incident light, the 180mm f/2.8 APO EX DSG HSM Macro Lens provides sharp, high contrast images even in backlit conditions. Providing additional length to the lens hood, the hood adapter provides effective shading to block out extraneous light. Accurate focusing Together with an OS function, you can get accurate focusing in any setting. With a rounded nine blade diaphragm, the 180 mm Macro Lens creates an attractive round bokeh at large aperture settings. Thanks to a Hyper Sonic Motor (HSM), you can achieve quiet high speed AF with a manual focus override that can be activated by simply rotating the focus ring.
