Having trouble with auto focus in the Aperature priority mode. When AF area mode is set for single area, the area of focus is just right of center. Is there a way to move the area of focus to the center besides changing to auto area AF? I am trying to shoot, relatively close still life for a catalog and would like the focus in the center. i know I can manually focus but Im wondering if there is a problem with the camera. It is a fairly new Nikon D80 with AF-S Nikkor 18mm-70mm lens, I have limitd experience with digital SLR's. Any suggestions?

Push shutter button half way to be sure camera is awake. Push control pad on the back of camera to change AF area to center. See if this works.

also make sure the "L" switch next to the directional pad is set to L.

when it is not locked the camera chooses the AF point, when you have it set to "lock" you can scroll thru any of the AF points with the directional pad to choose which AF sensor you want active.

Thanks Rooz, was not sure D80 had that feature. My D200 does, D50 does not.

Assuming the recommendations above don't work, I wonder if AF zone (normal or wide) would make a difference. You should probably make sure it's set to normal.

Is it working normal on Shutter Priority and/or Manual mode, or only failing on Aperture Priority?

Aside from that, try another lens...

Ooh. That's wierd. On the D200, you set the switch to L and you cannot move the focus point. That's the purpose, to lock the focus point so you don't accidently move it about (DAMHIKT).

I know the first time I played with manually picking the focus point, it didn't sink in that the four-way directional pad was the key, so I wondered how I'd ever get my focus back to the middle point for a while.:eek:

We're just a little more tech-savvy now.:cool:

What mode do I need to be in to use the 4 way directional pad to change the area of focus? FYI center AF area set to normal, AF area mode set to single.
Also does not seem to be working in shutter prioriy or manual mode.:confused:

Eileen,

One of the biggest differences between Nikon models is they way they handle auto focus. Let me recommend ByThom and his model specific 3rd party user manuals for the Nikon cameras. I don't know of ANYONE that has purchased his book(s) that has not been very satisfied, and felt it was easily worth their money. The biggest complaint I have heard about his books is that they should be free - FROM NIKON WITH THE CAMERA.

Here is a link for the D80 manual (http://www.bythom.com/d80guide.htm)

Buy it. That is my first line of advice. See everyone that really learns to use their DSLR uses their camera differently, ESPECIALLY for auto-focus.

Thom's book will explain to you how to choose the right AF mode for your style. Autofocus setup is not an "on" / "off" limited thing. You can set it for continuous, for single-shot, for whether the camera must lock focus before allowing the shutter to release, for closest-subject priority, etc.... It is really a compound setting, meaning more than one menu choice will determine how it will work for you.

This is just one of the reasons to buy the book. While you are waiting for Thom's book to show up on your doorstep, carefully read, re-read, and experiment (with the camera in your hand as you read again) the Nikon manual regarding autofocus settings.

As previously suggested, are you pressing the shutter button halfway WHILE using the 4 way dial to change the focus points? Also, make sure the Dial isnt set on the "L" position UNTIL you have selected the focus point you want, as that will lock it in and you wont be able to change it until you unlock it.

EDIT** Sorry T, we must have been typing at the same time.. didnt mean to bump your post out!

Look at the section called "Solutions for various shooting situations" and then "portrait basic" section.

It covers what we are talking about.

all cool jason,

The point I was trying to make - in my verbose manner - was that there are more than one setting that could be affecting the use of the 4-way for selecting the focus area. I could be wrong, but I seem to recall that when my camera came it defaulted to closest subject. That drove me crazy. I changed that setting, but it took me some aggravating trial and error and reading some harder to interpret sections of the manual to realize what was going on.

I knew the capability was there (from playing with one in the store pre-purchase) but it wasn't as intuitive as I thought it should be.

Thank you, thank you, thank you. That was it.
I will also get the book by Thom as suggested by tcadwall.:)
