I was thinking about how annoying it is when you are shooting wide open at a very low f-stop,m f/1.4 or f/2, and when you employ the focus-recompose method you will often end up with the eyes, or whatever your desired focus point is being off a bit. I came up with an idea of sorts on how a camera could combat this without the pain of selecting a focus point, which I really do not like doing- Let's say you are using center point one shot AF. You focus the center point on the eyes, and naturally recompose to a more pleasing composition while your shutter is half pressed. What if the camera would somehow detect that area, and assuming said desired area of focus falls under another focus point once desired composition is obtained, the camera automatically senses this and reconfirms the desired focus using the new, non-manually-selected focus point on the original area of desired focus? I imagine it would do this by employing a very small "snapshot" of the area under the desired focus when you half-depress the shutter, then on-the-fly sensing if this "snapshot" falls under any of the outer focus points while recomposing, where it will finally verify and correct the focus if it does fall under a new focus point. It's kind of hard to explain, but I imagine with how "smart" AF is getting (Not counting canon's "5" series of course ), this is not unrealistic... Any thoughts on this? Is it possible? More importantly, is is plausible?
