Hi... I am having a problem i never had before with my D90, after almost 2 years of usage. At some point i turned the focus mode on manual (on the camera), and when i switched it back to automatic it stayed on manual. Anyone has a solution for that without having to go to a FixShop? Because i live pretty far from civilization at the moment. Maybe if take out the M/A switch off the camera? would that help me? I mean, i don't even care if i can't switch it back... as long as it works on Auto... I need it for my job. Please help... Thanks

I don't know how much experienced you are with a digital camera. Don't even know you have any experience with any camera. But the modern camera's are capable of taking sharp pictures, is used right.
But to let the camera do its work correct it should be setup correct and used correct.
Let me explain.
Most camera's have a possibility to make pictures in automatic. (dail on the green camera symbol) But still there is more to do.
Every camera has a point (or more points, that are used to focus the picture. You can use to put that point where you want the picture be in focus. Most of the time that would be the centre of the frame. But the camera can't focus in theoretical a blink of an eye. It needs some time, to find the focus by differences in contrast, or patterns. A DSLR sometimes can focus in less then a tenth of a second. Compact camera's could need up to one second, before they are in focus.

So try to setup the camera to automatic. Place the focus marks (as described on page 6 of the manual. Then press the shutter realise button half and look if the camera can focus. If it can't, release the button and try again. When the pictures is in focus, then you can press the button fully.
On page 33 of the manual, there are different modes of focus. be sure you use the mode you chose in the correct way.

link to the manual I refer to.

Are you sure the M/A switch on your lense is on A?
Do you use an older AF lens? Among those are lenses, that have been fitted with a A/M switch.
Is the aperture lock on the lense locked.
Just some things to check before you go to a repair store.

The 9 you see is the maximum "burst" which is (pictures made in rapid succession) and is not an issue with your problem at this time the flashing green dot is the in focus confirmation light and it's good that you are seeing this as we will use it to remedy the problem.

What I want you to do is put the AF-MF switch in the manual mode if it's already in manual mode then that was your problem switch to AF and go take some pictures. If it's in AF mode switch to MF make sure teh camera is on and look through the viewfinder at a subject say 15 feet (4.5 meters) away something that has contrast then turn the manual focus ring on the camera slowly until it appears to your ey that it's coming into focus when it's in focus the green light will come on solid, now you know what you are looking for focus an several different objects at different distances and focus manually. Now switch the lens over to AF (auto focus) and focus on the same thing but let the camera do the focusing What auto focus will not focus on in something with little or no contrast like water clear blue sky a painted wall mirror chrome glass and a few other things.
Here is another diagram to check make sure you are in the correct mode.

Now for the focus point in the viewfinder make sure it's in the center position.

To adjust the focus point do this

Once you have the camera set to the center focus point and the correct AF mode (one shot) auto focus should return to your camera. Have fun Robert from London Ontario Canada

This is due to settings change
Please switch the focus mode to multi point focus or any other
current setting will be center focus or spot focus that is why only the center is focused and the rest is blurry
Please refer to your fuji manual for instructions on how to change the focus mode

Thanx and i hope this solves your problem
Please dont forget to rate this information

The camera is having problems with your lens and this is why it goues into the error mode. Try first cleaning the interface contacts on the lens ( see enclosed pic ) . If this does not sort the problem out then the auto focus motor ( or related hardware ) inside the lens will need attention. Also try other lenses to see whether it is only the lens ( I very seldom see this sort of problem cause by the body ; it is always the lens that gives this sort of trouble )

Change from auto focus to manual focus or focus using only one focal square and change the setting to One Shot. You may need to shoot in Manual (M) mode though. Any of the "auto" modes will not let you.

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.

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.

EXPLANATION.
1. The problem with 18-135 lens is because it make from plastic. Main problem from plastic is it can be reshaped after a few usage. When the shape ran out, the contact point will be defective. When the contact point didnt really touched, the processor cant send signal to lens to do autofocus (the lens focus using the lens motor, not the body). When u set to manual focus, the body doesnt need to instruct the lens to focus.
2. You are focusing something that is to near than the focal point.

SOLUTION.
1.Try cleaning the contact point on the lens. Then mount it back until the F showing up (F= aperture). This solution depend on your luck too. if the gap between to contact is so far, then it might happen back. Usually when u need it badly. haha
2. try to get more distance from your subject. Just keep press the shutter until the camera focus.

CONCLUSION
1.But new lens with metal mounting. It will last and durable.
2.Buy macro lens to close up. normal lens wont focus at short focal point!!~

When using manual focus(MF) and direct manual focus(DMF) mode, Flex Digital magnifier (FDM) can be used to confirm selected flex focus point by enlarging it to 4x. The focus point can be selected after enlarging.
