I'm not too non-technical but I have to say that while the D300 camera is fully featured, the D300 manual is certainly not.
My AF-selector mode switch seems to have 4 click stop positions although I was only expecting 3.
It stops at M, S and then once each on either side of the C. At the first side I get a full display of focus points. In the second (the last position on the switch) I get no focus points although it will take a picture and as the picture is taken, the selected point flashes into the viewer screen for a moment or two. However it seems impossible to influence the selection as the focus point is not visible.
What have I missed in the manual? Where am I going wrong?

What you have noticed is a "feature" of recent Nikon SLR's including the D300, D3, D200 and D2 amongst others. These cameras have a mechanical autofocus coupling (commonly known as "screwdriver"), in the lens mount surround. The coupling has to be withdrawn into the camera body when the camera is switched to M focus mode; this happens when the switch is moved from "S" to "M", and feels like an additional unmarked click-stop.
Thanks Brian, I noticed the same thing and called the camera store where I bought mine. We figured it had something to do with that since the switch doesn't have that extra detent when there's no lens attached to the camera.

Thank you very much for this information folks! I just switched over to Nikon and just recieved my D300 and I was wondering about this as well. Thought something was going wrong with my camera, but sure enough, took my 18-200 off and then used that switch and the mysterious fourth stop between S and M went away.
On more careful examination, I think that I have a false/phantom stop between the S dot and the M dot. Moving the switch from S-true to S-false doesn't alter any of the camera settings and at both positions the camera works correctly for the setting at S-true.
I think that I'll visit a couple of shops on Monday and see if I can find the same thing on other D300s.
Are there any good guides or internet links to the use of this quite complex focusing system?
The rest of the camera is pretty familiar stuff really but the focusing is new ground for me.

Yes I saw the post - but I missed the point you were making. (Obviously my own autofocus skills aren't functioning correctly at present.)
I see what you mean and I think that you must be right. I'm relieved.
Now where can I get some good info on using the focusing system
The D300 Digitutor from Nikon has some good video footage on using the focus system. Other than that, the manual is also fairly complete after you divide it up into functions and controls. Here's a link to the digitutor: http://www.nikondigitutor.com/eng/d300/index.shtml
Look first at the Focus Mode Selector - there you find Manual Focus, Continuous Servo AF and Single Servo AF. Once you are familiar with this, if you are using Manual Focus, you are done. If not, continue on to the Auto Focus Area Mode selector. Learn the different modes and where to use them. The Digitutor has a good section on the modes, and search the archives here.
Most importantly start taking pictures - see how the modes work and what kind of results you get.
