High performance, large aperture medium telephoto macro lens with OS (Optical Stabilizer).
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
With Super Multi-Layer Coating
No Super Multi-Layer Coating
Handheld photography with ease
No Optical Stabilizer
With Optical Stabilizer
* 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
Hyper Sonic Motor
Rounded 9 blades diaphragm
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 147mm F4 AF* telephoto macro lens, and APO TELE CONVERTER 2x EX DG as 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.
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.
* When taking photos with full-size digital SLR, please remove HA680-01 in order to avoid the edges of image being blocked.
