Overview

Description by Sigma:

  • Designed for use with full frame digital SLR cameras. May also be used with smaller APS-c size sensors with a corresponding effective increase in focal length to about 150mm with most cameras
  • Focuses down to 1:1 magnification ratio at its closest working distance of 12.3 inches
  • Extremely compact measuring only 5.1 inches long.
  • A hood adapter, lens hood, front & rear lens caps are included with the lens.

This large aperture medium telephoto macro lens offers advanced performance of close-up photography. Sigma’s own proprietary OS (Optical Stabilizer) system enables handheld close-up photography. A Special Low Dispersion (SLD) lens and one high refractive index SLD lens provide excellent correction for all types of aberration and distortion. A floating focusing system moves two different lens groups in the optical path to different positions. This system compensates for astigmatic aberration and spherical aberration and provides extremely high optical performance from infinity to 1:1 Macro.The Super Multi-Layer Coating reduces flare and ghosting, providing high contrast images. It is also possible to use this lens with Sigma's APO TELE CONVERTERS. The HSM (Hyper Sonic Motor) ensures quiet and high speed autofocus as well as full-time manual focus capability. This lens features a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image.

* Nikon mounts do not have an aperture ring. Some functions may not work depending on the camera model. *For Nikon and Canon mounts, Optical Stabilizer (OS) function will not work with film SLR cameras except Nikon F6 and Canon EOS-1V. * 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 the hood adapter if you are using these cameras.

Reviews

"What is also obvious from the comparison photo above is that the Sigma 105mm f/2.8 EX DG Macro Lens extends - by up to 1.8" (42mm) - when focusing. Although not a big deal, when you are using a lens that extends while working with close subjects, care must be taken to not bring the lens in contact with those subjects. The relatively small 58mm filter threads do not rotate when extended or retracted.
