Is my lens or my camera failing?

I am an avid non-pro Nikon D4 high school sports shooter. Before venturing to my next game, I'd like to know if anyone knows what is PROBABLY going on with my equiptment? Symptoms: using a 70-200mm VR II lens set for auto focus/action (I don't think any switches were mis-set) I shot many full continusous bursts of soccer. Upon processing on LR5 this is the results....some sequences begin focused & then gradually OR abruptly become way out of focus. This occurred over & over...some nice shots...many terrible failures.....without any nearby action until next game is there any help in trouble shooting or ideas to help me? Hoping for the best while preparing for the worst......

I think it would be best to show a few examples to make it easier to see what's going on. If you have a few good ones and a few not so good ones, it could also mean inconsisting technique, failure of equipment is hopefully the last option!

Sounds like either an auto focus malfunction or you didn't keep your focus point(s) on the subject while shooting.

Thx.....I really think it is an auto focus malfunction, but want to see if its the lens or the camera. By using a different lens next time I will know if the problem is with my 70-200, but I hate to miss game aqction while trouble shooting. Really think I need to wait until the next game....#@%!

The D4 usually tracks really well by the way.....this is a new & unusual problem.

dear Mr Bill, when shooting burst with the Nikon the camera is programed to make adjustments to each shot in hopes that some of them turn out. At lest that is what the manuals for all three of my Nikon's tell me.

Hope this sequence (although certainly not special) illustrates the problem.
I think it would be helpful to see where the camera was actually focusing on each shot. Perhaps that would give a clue?
Can you look at and show the focus point selection on your shots?

I have the focus point selected smack dab in the center all the time...not sure if this is recorede somewhere in metadata for actual shots tho.

Parts of your images REMAIN in sharp focus... the referee, the trees... one or the other background players.
I say camera and operator are probably the likely reason for soft photos.

It is.... if you use Lightroom, you should look at a plugin that will show the focus points used by the camera.
you can find it here:

Or you could use View NX2 to load and display the same information per image....
It would also help if you can state what focus modes you are using....
