Telephoto zoom lens incorporating Sigma’s original Optical Stabiliser 
 
 

 
 
 
 
 
 
 

 

 

 
The Sigma Corporation is pleased to announce the launch of the new APO 120-400mm F4.5-5.6 DG OS 
HSM. 
 
This telephoto zoom lens incorporates Sigma’s original OS (Optical Stabiliser) system.  It offers the 
equivalent of using a shutter speed approximately 4 stops faster.  
 
Three SLD (Special Low Dispersion) glass elements provide excellent correction for chromatic 
aberration.  This lens is equipped with the rear focus system that minimises fluctuation of aberrations 
caused by focusing.  It provides optimum image quality throughout the entire zoom range.  The super 
multi-layer lens coating reduces flare and ghosting. High image quality is assured throughout the entire 
zoom range.  
 
The minimum focusing distance of 150cm  throughout the entire zoom range and has a maximum 
magnification of 1:4.2 make it useful for close-up photography.  This lens incorporates HSM (Hyper Sonic 
Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override.  
 
The addition of the optical 1.4x EX DG APO or 2x EX DG APO Tele Converters produce a 168-560mm 
F6.3-8 MF ultra-telephoto zoom lens or a 240-800mm F9-11 MF ultra-telephoto zoom lens respectively.
