Originally posted by IchabodCrane I've been under the impression the better way to test this is to de-focus before you activate the AF. That way you force the camera to focus and can see how well it does.
Right, that's my approach too. Intentionally defocus and use the PDAF to focus on the target. Then switch to manual focus, engage magnified live view, and see if there's any improvement to be had, making a note of which direction the focus ring needs to be turned.
Make adjustment and repeat ad nauseam.
