With these settings, you also have "AF on demand". Your (focus) setting is stored until you change it (via AF or MF). > > However, what's even more practical is *pre*-focus, instead of > *after*-focus....that way you can cut down focus time significantly, > while also preventing hunting for focus in low light/low contrast > situations. Yes, absolutely. It also helps to prefocus when you shoot very fast objects, like e.g. racing cars. The camera locks on much quicker then after you press the AE-lock button.
