I have a Sigma 150-600, on a Nikon D7200. I am very pleased with it. There 3 settings on the lens for focusing at different distances, Full or 10m-infinity or 2.8m - 10m. As the lens focuses very quickly what is the advantage and main use of these settings?
 
The main use is to stop any risk of the lens wasting time trying to focus in areas you don't want it to, for birds i mainly used the 10m to infinity, insects flowers etc the 2.8 to 10mt
