Because the second was not given time to focus either.Those times are Exif Capture date, but not sure that much movement could happen in 0.13 seconds? Might be affected by processing?But if you are going to use AF-C, either depend on the second picture, or learn to hold half press a second to let if find focus first.Whereas, if you used AF-S, you press shutter, the kids move, the lens finds focus, and then the shutter activates.  Seems a better plan.The disadvantage of AF-S (if we could imagine to call it a disadvantage) is that the shutter is delayed until it finds focus.  However, this seems a big plus to me.  <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />AF-S just focuses once, and then half press holds it regardless (but it does focus first).The advantage of the AF-C default is that we can hold half press, and move the camera aim all over, at near things and far things, and the lens will go crazy trying to keep up with focus.  Or the subject can move, same thing, the lens focus will try to follow (assuming we hold half press).   But at the instant we choose to full press, the AF-C default is that the shutter will trigger immediately, regardless if it has found focus yet or not. But focus really does sort of matter.  We might have more leeway at f/16 than at f/1.8 however.</blockquote>
