    I was using AP mode on my Nikon. Doesn't that automatically set my shutter speed? I don't remember having these problems in the past. I know is a very newbie problem. Sorry

    It appears that your camera did focus ... but just behind the two foreground subjects.

    ^^^ Yeah. The kid on the far right (red shirt & socks) looks to be in focus.

    What focus mode were you using, and which focus points were selected?

    right. However... I was obviously trying for the one with the ball. I don't get what happened. I think my f stop is the problem. Should I have been up in the 8+ range?

    I think I was using spot with single focus point. I was trying a number of different things.

    Right, I figured that. ;)

    F stop has absolutely nothing to do with autofocus.

    What likely happened is that you had the wrong AF point selected, or you had all AF points selected (and the camera chose the wrong one).

    Either that, or you didn't half press the shutter release to lock focus and then press all the way to capture. If you do it all in one smooth motion, the camera will have to decide what to focus on on the spot.

    OllllO -
    Normally... I would totally agree. But those were not the only picts that turned out like that. I will post more tomorrow because I need to get to work. I can still get on here, just not post pictures. Stupid Air Force computers.

    Agreed, this is a matter of where your autofocus points are.

    There might be a problem if nothing were in focus, but it looks like it is just the wrong subject.

    That makes is sound like Josh's first guess is a likely candidate, that you had an inappropriate focus sensor selected. Either that or your handling the camera wrong, trapping the focus without properly targeting the subject or waiting too long after trapping focus and the subject moves before you take the shot.

    Other than what has already been mentioned, I don't really know what could have caused it. I doubt it's a fault with the camera...

    No offense, but I think the most likely thing is that 'in the heat of the moment' you forgot to lock focus in before taking the picture.
    OR - you did lock in the focus, and everyone moved before you took it.

    The camera did focus on something, so I think this one is "user error". Not trying to say you don't know what you're doing or anything like that - this just doesn't look like a camera problem to me.

    HAHA..., Trust me - I know. ;)

    I'm sure its user error. I'm kinda new to all this.

    My other question... based on the f setting shouldn't the shutter speed been a little faster? I know is AP setting you don't have control over that aspect. But still

    If you would have used the 4-way controller on the back of the camera, and pressed the left hand side of the button you would have put an AF bracket on the kid in the red shirt, and you would have had perfect focusing.

    On the D700, a better solution for soccer would be to go to the Custom Settings menu a8, and select 11-area AF...use the thumb button to put a group of AF points on off-center subjects and you'll have superb autofocusing.

    What happened here is that the active AF sensor is in the middle of the viewfinder image--leading to what is called back focus, ie focusing in back of the desired subject.

    The AF systems in modern cameras are very sophisticated, so you need to read the manual and also do a bit of practicing.
