The Sigma USB Dock paired with Sigma Optimization Pro software brings lens customization to an entirely new level. Photographers can now personally update the firmware of Sigma’s new Global Vision lenses and make performance enhancements including multi-zone microfocus adjustments of +/-20 from the factory default settings.
One of the benefits for outdoor sports shooters on APS-C sensors is the gain in reach with telephotos lenses. The negative of course is that now your wide angle 16mm is now not so wide at 25.6mm. Thankfully Sigma has a great wide-angle lens perfect for crop sensor shooters…the 10-20mm f3.5! I picked up this lens about a year ago and have shot outdoor sports and adventure travel with it extensively.
