by the time you're experienced at more aesthetically balanced compositions...

AF points are IDEAL if put narrower/closer to center, just outside key pts, than wider:

0.333/0.667 [one thirds positions]: risk overcropping compositions, this is why 3x3 grids exist for beginners to composition (the cross '+' pts matter for 'targeting') [too wide; hit and miss; proportions are amateurish; hardly aesthetic at all; unrecoverable 'bad' compositions.]

0.375/0.625 [3/8ths and 5/8ths positions]: closest to golden ratio (best to use AF points INSIDE these points), this is why 4x4 grids exist at all [the unobscured center of the 'box' of the grid matters more than the '+' cross points (ignored)], who no longer use 'one-thirds' at all, but are progressing to 'golden ratio' without really realizing it. [almost there; inner AF pts have proper undercrop leeway for flexible post-cropping]

0.382/0.618 [phi (golden) proportional divisions]: AF points ideally INSIDE these two key points [most mfrs have key AF points 'just' within these positions] those who use these 'inner' AF points know, they're rigged for 'golden ratio undercropping leeway'. [just right, max flexibility, minimal lost compositions]

by the time you're experienced at more aesthetically balanced (natural) 'golden ratio' compositions...

you'll actually start using JUST the center AF points, because you 'see' it... when composing (center focus, then moving off-center to that key point becomes natural (naturally fast, too))

you could do either. usually if your subject is in the same position, and you want to do repeat shots, then it makes sense to use the four-corner ones instead of just the center one.
