Originally posted by Digitalis I know people who actually do that.
Using SEL-1 for much of their everyday shooting? Well, I actually happen to do so, primarily because I've come to distrust focus-and-recompose. And I don't consider myself a sports or action AF guru or anything.
I have found that in combination with back-button AF I have become much better at nailing shots of people (usually family), zoo animals, and pets. Either I move the AF point around to come to lie on the point of interest (usually the eyes, or the closest eye). Or I pre-select an off-centre AF point that fits my compositional intention and wait till the subject moves to target. Spray and pray, I hear people hissing, but with a little practice it goes beyond that, as you become more nimble at moving and/or anticipating the AF point (or the SEL-9 AF points I have occasionally used as a variant). Admittedly, it works best for subjects that are not moving about that much, or are temporarily at rest.
Keeper rate that way? Not stellar, not even close, but I usually return with a couple of nice shots where the focus is
dead on. And those are the ones I'm after.
