The APO Macro Sigma 180mm F2.8 EX DG OS HSM is a high performance telephoto macro lens designed for Full Frame sensors but may also be used with smaller APS-C size sensors with a corresponding effective increase in focal length to about 260mm with most cameras. The 180mm F2.8 has a large aperture to handle any lighting scenario and the macro capabilities allow focusing down to 1:1 magnification ratio at its closest working distance of 18.5 inches. A Hyper Sonic Motor (HSM) ensures quiet, high speed, and accurate autofocusing while an Optical Stabilizer (OS) compensates for camera shake when shooting hand held. The 180mm F2.8 macro also incorporates a floating Internal Focusing system which reduces aberration during shooting working together with three FLD ("F" Low Dispersion) glass elements for superior correction of color aberration. This lens has a rounded 9 blade diaphragm creating an attractive blur to the out of focus areas of the image and is also compatible with Sigma APO teleconverters.
- Large aperture optically stabilized macro lens
- FLD glass elements, performance equal to fluorite
- Includes: Carrying case, lens hood, front & rear caps
DG for Digital
Designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35mm SLR film cameras and APS-C size DLSRs.
In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.
OS Optical Stabilizer
This function utilizes a built-in mechanism that compensates for camera shake. It dramatically expands photographic possibilities by alleviating camera movement when shooting by hand held camera.
HSM Quiet & Fast Autofocusing
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
IF Inner Focus
To ensure stability in focusing, this lens moves the inner lens group(s) without changing the lens' physical length.
CONV Teleconverter Compatible
This lens can be used with the APO Teleconverter EX. It can increase the focal length and will interface with the camera's AE (automatic exposure) function.
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
