Sigma Optimization Pro and USB Dock: Screencast Demo

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.

Sigma Global Vision lenses can be customized through the USB Dock and Sigma Optimization Pro software. As you can see, we’ve customized several lenses so far!

These adjustments are possible for every DC and DG lens in the Art, Sports, and Contemporary lines. The Sports line of lenses, represented currently by the new 120-300mm F2.8 DG OS HSM | S lens, allows for even more performance enhancing tweaks to be applied–autofocus speed, focus limiter, and Optical Stabilizer performance.

And with two custom settings accessible through the on-lens switch, it is possible to have three sets of performance parameters: Factory settings, C1 and C2. Because when it comes right down to it, photography is about personal vision, and while a photographer working a turn on Giant Slalom ski racing is going to want blazingly fast autofocus, with a focus limiter set to cover that certain distance,  a wildlife photographer in a blind beside an eagle’s nest waiting for fledglings might want the AF to be a bit more methodical over a different, much closer focus limiter range.

Microfocus can be adjusted in four zones, and with zoom lenses, at different focal lengths.

Overall, as the screencast demonstrates, operation is easy and intuitive within the graphical interface of Sigma Optimization Pro. And once the firmware is rewritten, it is, honestly, amazingly satisfying as a photographer to observe the custom changes in effect through the viewfinder! The factory AF speed is swift as it is, but combining the Speed-priority AF setting and a custom focus limiter really makes it fly!

Autofocus Speed can be speeded up or slowed down, depending on your preferences.
You can set your own near and far focus limiter points.
You can select from Dynamic, Standard, or Moderate OS settings to control the feel of the OS operation while framing through the viewfinder.

Next up for me is an in-depth hands-on field report with the Sigma 120-300mm F2.8 DG OS HSM | Sports lens in action. Check back around May 9th for that!
