• * For Sigma SA mount
  * Sigma SA and Sony mounts has been discontinued in production.
  * Nikon mount of this lens is not equipped with an aperture ring, therefore, depending on the camera model some functions may not work.
  * This lens cannot be used with film SLR cameras with the exception of the Nikon F6 and Canon EOS-1v.
  * When using the OS function of a lens with a camera which incorporates a stabilizer unit, please turn the camera’s stabilizer unit off.
  * When using the APS-C Hood Adapter HA680-01 with digital cameras with larger than APS-C size image sensor, vignetting will occur. Please remove he hood adapter id you are using these cameras.

• 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 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.

• 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.

  

• 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.

  

• Handheld photography with ease

  Incorporation of the OS function offers superior stabilizaion As the stabilisation effect is visible through the viewfinder, it aids composition and accurate focusing.

  * The OS effectiveness will gradually decrease as the shooting distance becomes shorter.

• 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 which have a strong light source in the background such as lights shining on the surface of 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 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.
