Oh sorry, just slang for finish adjusting. It was mentioned above to wait a half second after pushing the shutter release in to give VR a chance to finish, or in my reference settle in. A phrase I remember being used growing up, for instance, a new family moving into a house might take months to settle in, unpacking, moving furniture around getting things jut as they want them and comfortable, or a piece of equipment with new parts installed would sometimes take a bit of settleing in to get worn in or broken in to work optimally. Always surprises me the terms I find common place are not that common place out of my region.
In the region of Iowa I grew up every would say Where you goin to? Instead of where are you going. Or instead of How have you been they would say How've you been doing? Gotta love it! Looks like I digress again sorry! Later Bertotti
