¶ Lens Features
EX LENS
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
DG 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.
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.
APO APOCHROMATIC
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.

¶ HSM
HSM QUIET & FAST AUTOFOCUSING
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
¶ CONV
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.
¶ Camera Specs
The Sigma 120-300mm F2.8 EX DG OS APO HSM is a unique lens in the photo industry. Its design is based around high speed superior optical performance. Created for Full Frame sensors, it may also be used with APS-C sized sensors as well. It has an array of technology to guarantee the highest level of image quality. This technology includes a Hyper Sonic Motor (HSM), an Optical Stabilizer, Inner Focusing and Zooming System, SLD and FLD Glass Elements (FLD has a performance equal to fluorite). The HSM ensures quiet, high speed, accurate autofocusing while the OS allows for use of shutter speeds approximately 4 stops slower than would otherwise be possible. Super Multi-Layer coating reduces flare and ghosting working together with the SLD and FLD glass elements for maximum correction of chromatic aberrations. An inner focusing and zooming system produces sharper images throughout the entire zoom range. With a large fixed aperture of F2.8 the 120-300 is capable of handling any lighting scenario.
