 150-600mm F5-6.3 DG OS HSM | C  
 The Sigma 150-600 millimeter 5-6.3 DG HSM OS Contemporary  was created around the concept of maximum portability meets utmost image  quality in a variable aperture hyper-telephoto zoom lens. Light weight  and compact, this s zoom can handle any long-reach photographic  situation one may encounter. This 150-600 millimeter Contemporary boasts  updated Sigma technology such as a quiet and optimized Hyper Sonic  Motor (HSM) and a new Optical Stabilizer (OS) with an accelerometer for  improved panning photography both vertically and horizontally, essential  for birding, wildlife and motor photography. The Sigma 150-600  Contemporary also touts a new zoom lock switch that can be locked at any  focal length and a new manual override (MO) switch is incorporated for  improved focusing control. Working with the Sigma USB dock, this lens  allows for maximum customization such as firmware updates and  adjustments to the focus limiter, AF speed and OS view. 
 Sigma has developed special software (SIGMA Optimization  Pro) that can update the lens firmware and adjust parameters such as  focus. In addition, the lenses from our Sports line have customizable AF  speed, focus limiter, OS function and full-time manual focus function.  The 'Custom Mode Switch' is the device for further customization on the  dedicated lenses. 
 In addition to AF/MF, MO (Override) is incorporated as one of the  options of the focus mode switch. By setting it to the MO position, it  switches to manual focus by rotating the focus ring even during  continuous AF. With AF position, standard full-time manual focus is available. Using the optional SIGMA USB DOCK, it is possible to adjust  the MO position’s sensitivity to switch to manual focus
