If you're glassing from out past 100 yards to two miles, does depth of field matter as much? It seems like once I get focused on one or the other distance everything is in focus with both my Nikon ATBs and my Swaro rangefinder.

It would depend on the magnification. For 10x binoculars and under you most likely will not have to refocus much, if at all, past 100 yards. Above that I cannot say as I don't use that high of magnification in binoculars.

As you get closer, dof decreases.  So with 6-8x, the focus will be more infrequent at distances past 100 yards. Focus still needed at times to seperate detail from brush at times, but the dof is less critical.
