Focus points I am suppose to see 51 focus points when look in my viewer and I only see one now. How can I change it back. Secondly the dynamic AF area one shows one focus point. When shooting.

All your questions are in regard to AUTO FOCUS MODE which is described very nicely in the manual. For d 72 that is Dynamic 72 point focus. That is on page 106 of your manual. The AF-C and AF-S are the focus areas. AF-S is single focus for stationary objects. AF-C is continuous where what you are shooting is moving. This is described on page 101 in your manual.

In the manual from page 62 and on, you see how to set.
You need the

and the

With the AF-area in the middle setting (Dynamic area AF) you can select 9, 21 , 51 focus points or 51 point 3D tracking.
The manual is still online for free here:

You choose the focus area with the cursor button. It can be locked with the switch below it !!! Several settings can be monitored in the top display, 5 points for the scenery programs, chosen area for the M A S P programs. This is also a nice way to monitor what all the scenery programs do with the settings. Good luck (check the lock switch)

The D90 has three different autofocus modes. In the AF-S mode it will not shoot until it has focused. In the AF-C mode it will shoot when you press the shutter release button even if has not focused. In the AF-A mode the camera switches between the AF-S and AF-C modes so either can apply.Also, bear in mind that the camera doesn't really know what you're taking a picture of. It may focus on something other than your subject. If you're in the single-area AF mode then you control which of the eleven focus points the camera uses. In any of the dynamic-area AF modes the camera decides.For full details on how the various modes work, please consult your manual. You might also check out the Nikon D90 video tutorial.

Hi, On the D7000 you need to press the button on the side of the camera that's in the middle of the AF/M switch and then you use to switch to decide whether it's in 1 point autofocus (hence forth called AF), 9 point dynamic area AF, 21 point dynamic area AF, 39 point dynamic area AF, 3D tracking AF or auto area AF. If you need more help with switching AF modes let me know and I can help you out =)

The D40 Dynamic area focus starts on the centre AF area then moves the focus to follow the subject.
The camera has followed something to the right and selected the right focus area.
This is normal.

You could select Single Area in the menu and move the area back to the middle using the rear AF Sensor Selector.

In creative mode I would imagine that you are required to choose the focus point. Try the arrow buttons.

Try checking C.Fn III, 3: AF point selection method. Yours might still be on option 2.

0: Normal - Works by pressing the AF Point button and then the Multi-controller.

1: Multi-controller direct - Press the multi-controller to directly select an AF point (without first having to press the AF Point button). Pressing the AF button reinstates all AF points for auto AF point selection.

2: Quick Control Dial direct - turn the Quick Control Dial to select AF points. In this mode, AF points will not be displayed on the LCD panel.

I had this problem awhile ago - you must have accidently adjusted the focal area - it is sooooo easy to do without realising it. Here is what I was told:
**************************

Most likely, you have changed the AF point, which only takes effect in the creative modes (Manual, Av, Tv, P, etc)

There should be a button on your camera that has a grid like pattern above it, like
-
- - - - -
-

or so. press that, look through the viewfinder, and move the shutter or rear wheel, you should see the different AF points like up in red, and as you turn different ones will light up, and eventually all of them. also, you can look on the screen on top (or back, if its a rebel) and it will show you which ones are selected while in that mode, instead of looking through the viewfinder.
