while looking at EXIF data, i notice some pictures say AF section centre, others say left and i even see right???
obviously i want it centred, i even have it at spot metering???
what gives....is it because it was shooting hockey and the subject moves??
thanks

Manual, pages 64-74: Focus, pages 75-87: Exposure
There are five focus areas on your camera, and a plethora of ways that the focus point can move, some of them automatic, some manually. It's easy to do by accident. On page 66, you'll find the instructions for the focus area lock, which you can set to prevent yourself from accidently moving the focus area.
Oh, yeah, and you might think, "I'll bet he's looking at his D200 manual". Nope, nor did I memorize the D70 manual. The jerks who stole my camera didn't get the manual. It's a useful read.
Metering and Focus are two distinctly different things. Focus sets the lens elements so that the image is sharp. Metering is only concerned with getting the right amount of light on the sensor, and is basically controlled by aperture and shutter speed.
And, yes, there are modes where the focus area will move due to a moving subject. Since you have to go into the menu to get to them (I think, see your manual), I'd be surprised if that's the issue.

I found I made the same mistake more than once. After I would
scroll through pics I had taken, using the left and right arrows on
the multi selector, the focus area lit very often was the last
direction I moved the multi selector. After doing anything with the
selector, I make a point of checking the focus area at the bottom of
the viewfinder display before going back to shooting.

With my Canon the focus point shows up as a red light in the display, does the D70 not show the used focus point?

You can check the focus point on the info LCD (left side)or through the viewfinder (highlighted brackets).

Thanks, that is what I thought... I do not understand how you then by accident can use a wrong focus point though.

Sad thing is, I had my D70 for 4 months before I knew I could move the focusing brackets position between all 5 focus areas. such a newb! But now that I know, its great!

If someone is unaware of multi-area focus (i.e. moving from an all-in-one to a dSLR), and missed it in the manual, then they can easily use the wrong focus point. This is a pretty common error, and according to a sales source is the cause of some returns for suspected focus problems.
Multi-area focus is one of the nice features of a dSLR that we all expect and take for granted, but many new users are just unaware.
P.S. Here is the viewfinder view. You can see the 5 AF focus points. The grid overlay is very handy as well

As a complete novice I hope that my stupidity offers some kind of help to another new user. I was trying to photograph my kids indoor soccer game, when the focus problem happened. It happened a few times that day before I realized what I had done. Coldrain, you sir are absolutely right that I should of seen it before the picture was taken. I guess I got kind of excited just to get my kids in an action shot and didn't pay attention to the highlighted focus area. I had zero knowledge about dslrs 2 months ago, but thanks to you guys and my lurking around here on this site, it's growing. You all are most helpful and patient.
Long way to go-Rich

I just want to say thank you all for this thread. Even though I have my D70s for over two months, I haven't read the manual yet (until this week). Last week when I got my 50 mm f1.8 len, I notice this focus problem. Some of the replies prompted me to research and read the manual. Now I really love my camera. :D

update....i forgot about this thread....lol
since i am working hard i came across this tidbit at nikonians...maybe ESOTERRA could of save us the trauma and explained HIS epiphany
anyway...apparently (will try when i get off work) you can half press the shutter down and use the scroll pad to move the focus point....some of us may have accidently done this by mistake......i think i will try and lock mine in on centre
sidenote....pretty hard to see that quick redlight indicating the focus sensor....argg
