I think it is time to have some confidence in your own ability and experience. You should be able to take a camera out of it's box, put a lens on it, and within the usual parameters that affect quality, get sharply focussed pictures every time.
If that doesn't happen, you read this forum and come to the conclusion that you are doing something wrong, you don't know the camera, it is so sophisticated you need to adjust this or that, post some details, no body else has this problem etc,
I had that kind of doubt since Christmas Day when I took the first shot with my D7000. Since then I have persevered through the trough of despond as so many shots have to be dumped, so many opportunities lost, so many sub standard shot have to be lived with because that's all I've got. The amazing super fast accurate focus system proves to be great at doing sharply focussed ears and blurry eyes even with well proven lenses, usually at the most inopportune moments.
Well, I've had enough of this. I know how to take a picture, compose, focus and get the shot, I don't need to be told how to do these basic things, or how to read an instruction book as if I was a novice, and a couple of weeks ago I nearly threw the thing in the river.
It's now in a Nikon repairer in Glasgow waiting to be fixed under the warranty. I phoned them today to see how it was going(still in the queue) and they confirmed that they were doing his kind of thing all the time - it's not an imaginary phenomena. HOWEVER the camera companies only allow them to give very vague repair reports, leaving it to the imagination of the victim and the internet to fill in the gaps.
So, PHOTOMAN2112, don't waste your time posting questions about the problem or feeling you need to defend yourself here any more, despite the nay sayers, your camera is clearly faulty if it cannot do what can easily be done with older "inferior" models. If your latest replacement doesn't give you sharp shots of someone's face in bright light within 5 minutes, give up with it, go back to the D700 or 300s, or TRY OUT IN A SHOP a different new camera model. That's my plan for when the D7000 comes back from the repairer anyway.
My biggest regret, apart from buying the brand new body mail order, is that I allowed my own confidence and judgement to be so undermined as to put up with the useless thing for so long, instead of sending it straight back!
