Sigma tele lenses - Custom OS modes - Dynamic or Moderate?

[SRT201]

On the Sigma tele lenses with the two-position "Custom" settings switch there are a number of options for AF speed, custom focus limits and OS behavior.

Does anyone know what the "Dynamic" and "Moderate" options really do for the Sigma OS?

I don't expect either of these is some hidden setting that's superior to the standard OS1 or OS2 but they do change the OS behavior. When these settings might be handy is a question.

Excellent! Thanks for the link!

I wish they had provided more than 2 seconds of demonstration video along with the still somewhat vague explanation of the settings. :-|
