High performance, large aperture medium telephoto macro lens with OS (Optical Stabilizer). SLD glass provides good control of aberration and the floating inner focus system ensures high rendering throughout the focusing range. By using Sigma’s APO Tele Converter, it is possible to take photos at greater than 1:1 magnification. HSM ensures a quiet and high-speed AF as well as full-time manual focus override. This lens has a rounded 9 blades diaphragm which creates an attractive blur to the out of focus areas.
Large aperture medium telephoto macro lens
This medium telephoto macro lens allows you to maintain an appropriate distance from subjects while still getting close up photos. Since the working distance at its closest focusing position is 142mm, shadows of the lens and camera will not affect photography making it suitable for taking photos of subjects, such as flowers, under natural lighting conditions. In comparison to the Sigma 50mm and 70mm macro lenses, the main subjects can be defined with perfectly smooth and blurred backgrounds.
High rendering performance
The lens power layout produces excellent optical performance. High refractive index SLD (Special Low Dispersion) glass corrects chromatic aberration, spherical aberration, and field curvature. It ensures high rendering performance at all shooting distances. The Super Multi-Layer Coating reduces flare and ghosting, maintaining quality images with high contrast.
Handheld photography with ease
Sigma’s OS (Optical Stabilizer) system offers effective correction of approximately 4 stops. As the stabilization effect is visible through the viewfinder, it aids composition and accurate focusing.
* The OS effectiveness will gradually decrease as the shooting distance becomes shorter.
Floating inner focusing
This lens incorporates floating inner focusing which moves two lens groups separately. This minimizes aberrations which occur as shooting distance changes and enables stable rendering of the image from infinity to 1:1 magnification. This also corrects image distortion, especially when taking close-up pictures. Since focusing does not change its overall length, this lens is easy to hold and use.
Quiet and speedy AF
HSM (Hyper Sonic Motor) provides quiet and high-speed AF. It is also possible to use a full-time manual focus, even if the lens is set to autofocus.
Rounded 9 blades diaphragm
This lens has a rounded 9 blade diaphragm which creates an attractive blur to the out of focus areas. This also creates smooth, rounded out of focus highlights when taking photos that have a strong light source in the background such as lights shining on the surface of the water.
Dedicated hood adapter
When taking photos with APS-C sized digital SLR, the (supplied) dedicated hood adapter, which extends the length of the hood can be attached. This gives more protection from harmful lights that could negatively affect image quality.
