More Detail:

• Life-Size Imaging: Achieve a 1:1 magnification ratio for true-to-life shots.
• Steady Shots: Optical image stabilization ensures sharpness even in handheld photography.
• Low-Light Excellence: Fast f/2.8 maximum aperture allows for shooting in dim conditions and achieving a shallow depth of field.
• Consistent Sharpness: Floating internal focusing system maintains image clarity across the entire focus range.
• Smooth Bokeh: Rounded 9-blade diaphragm crafts a soft and pleasing background blur.
• Advanced Optics: 16 elements in 11 groups, including 2 SLD and 1 high refractive index SLD element, combat aberrations.
• Flare-Free Photography: Super Multi-Layer Coating minimizes unwanted flare and ghosting.
• Swift Focusing: Hyper Sonic Motor (HSM) ensures rapid and accurate autofocus.
• Built to Last: Sturdy metal construction paired with weather sealing offers protection against the elements.

• Quiet and speedy AF - HSM (Hyper Sonic Motor) provides quiet and high-speed AF. It is also possible to use full-time manual focus, even if the lens is set to autofocus.
• 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.
• Floating inner focusing - This lens incorporates floating inner focusing which moves two lens groups separately. This minimizes aberrations that 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.
• 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 - Incorporation of the OS function offers superior stabilization As the stabilization effect is visible through the viewfinder, it aids composition and accurate focusing.
• 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.
• APO Tele converters - This lens is compatible with Sigma’s APO TELE CONVERTERS. With APO TELE CONVERTER 1.4x EX DG, it can be used as a 147mm F4 AF* telephoto macro lens, and APO TELE CONVERTER 2x EX DG as a 210mm F5.6 MF telephoto macro lens. This allows a greater working distance while still achieving 1:1 macro magnification. *AF does not work from 0.45m close-up photography.
