Understanding Camera Autofocus 's link ( http://www.cambridgeincolour.com/tutorials/camera-autofocus.htm ) is supporting your comment, specially the statement.... (Further, since the central AF sensor is almost always the most accurate, for off-center subjects it is often best to first use this sensor to achieve a focus lock (before recomposing the frame) .... but, what is the allowable tolerance here .. i.e, what is the limit beyond which we can say that there are a focusing issue @ the off center focusing sensors ? .. Thanks

So why are there 51 of them? Is this a joke? If the only accurate AF point is the centre one, and that's the only way I can get true 36 MP resolution, Nikon maybe should have thought a bit more carefully about this camera release.

Center Af is not the only accurate ... it is the most accurate
