Because my subjects often move, one of the most critical components of any camera for me is its autofocus system.  What's the use of a very high resolution sensor with extremely low noise if the shot I capture is blurry - not because of subject movement but because the subject is out of focus?

In this post I will discuss my experience regarding the Nikon D600's autofocus speed and accuracy.  I will also discuss the clustering of autofocus points.

(And even though you may not be in the market for a D600, you may be interested in reading about a couple of alternatives to focus-and-recompose.)
