SOURCE: Camera won't autofocus

I too had D50 autofocus problems and ended up buying a new D300. I then learned that my issue was in the focus areas. The D50 has five focus areas. As you look through the lens, you will see one rectangle in the center and four to the top, bottom, left and right. You should make sure that the center rectangle is highlighted. Use the round thumbdial on the back of the camera to move the focus area.

SOURCE: Nikon D40 will not focus when shutter pressed 1/2 down

has the lens stuck up? put it temporarily on 'M" and try to turn the focus ring. this should be freely turning;

otherwise you may want to check the camera body to lens electrical contacts (silver).. a small dab of alcohol to a q-tip.. make sure its not that wet..then try to clean the contacts.

SOURCE: My d90 camera focus dosent work in af it keeps

Auto focus works by detecting differences in contrast. If you try to focus on something with no contrast, the camera will have trouble focussing. Try aiming the camera at something else the same distance away and keep the button pressed half-way while you re-compose the shot.

SOURCE: D40 with a Nikon AF-5 DX 55-200 lens will not auto

I had a similar problem with one that I bought. and come to find out, the gears internally in the lens where broken. I would return the lens, and get another one. Also when you go to buy a lens for your camera make sure that you bring the camera with you to test the zoom before you buy it.
Just FYI you also need to remember that with a smaller zoom your focus time will be slower, and it will take getting use to, unlike the larger zooms, you are trying to focus on a large area but being very detailed at the same time.

SOURCE: Scratched lens

Trying to repair a scratch on the front of a lens is impossible without changing the focus of the lens. You will never be happy with the results.

HOW DO I SET MY CAMERA TO AUTO FOCUS


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.

When trying to take a picture the lense moves back and forth trying to focus. When it finall stops the subject is out of focus. There is a grinding sound as it tries to focus. Some times the picture will...


It sounds like you need a new lens. This particular camera does not have an autofocus motor built in, which means it can only use lenses that have a motor already built in. Look for any Nikon lenses that have the AF-S in their name.

Amazon Search for "Nikon AF-S": http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=Nikon+AF-S&x=0&y=0

This is also a good "general use" lens: http://www.amazon.com/Nikon-18-55mm-3-5-5-6G-AF-S-Nikkor/dp/B000LWJ1ES/ref=sr_1_10?ie=UTF8&qid=1298926690&sr=8-10

Hope this helps.

I try to take a picture in AF mode while the confirmation light in the viewfinder blinks, a picture cannot be taken, but in MF mode picture taken correctly what is the problem?..


It's attempting to tell you that AF has failed. I'd expect low light, low contrast, reflective subject like a mirror or chrome. A solid colour wall with no contrast will also cause a AF failure. Auto Focus relies on contrast. Switching to manual mode shuts off the system and you can take a picture with nothing in focus.

D80 auto focus broken


AF lenses normally have a subtle grinding noise when used. Make sure your AF switch is turned on. If this still does not work, you may wanna consider bringing it in for repair

Camera will not focus...makes screaching noise in auto mode


Hi cham4017, It sounds as though the lens has grit or dirt or the like in the zoom. You could attempt to vacuum it however, I suspect it will need to go to Nikon for cleaning. I have mentioned this to others, the 18-55 is not well weather sealed as a pro lens is. Realize this is an inexpensive consumer lens. One major difference between consumer and pro lens is the weather sealing.

Autofocus on my Canon 28-135mm f/3.5-5.6 EF IS fails


Hello. First, check the contacts on the lens mount--you're looking for bent pins, oxidized(odd-colored) metal, damaged contact points, etc. The camera must communicate reliably with the internal circuitry of the lens unit. If there is any dirt, moisture, intermittent contact going on, the sensitive focusing electronics will be effectively blinded. If all is fine with the contacts, then the problem lies with the circuits in the lens that provide critical focusing data to the camera. Movement of certain parts causes electrical changes to occur at a calibrated rate--if the camera loses connection, it can't tell if the lens is actually adjusting. You'll have to send the lens in for repair--http://www.usa.canon.com/consumer/controller?act=SupportIndexAct. This address should get you started.--Hope I helped!---Rick

Hey Embroiteri,
I hate giving out bad news, but it sounds to me like your focusing motor is broken. I am of course going on the assumption you have the camera set to AF mode, and the lens still doesn't focus. In my experience with SLR lens is that if there are scratching or grinding noises when either focusing or zooming there is almost always something broken inside.

Sincerely,
Allan
Go Ahead. Use Us.

Nikon Auto focus problem with the 18-135 KIT lense


I had this problem and just realised it today. I found out that it was a a settings problem. What I had done without realising was I had my "AE-lock" button functioning as "AF-ON" which meant that my autofocus would only turn on when I held the shutter half-way and pressed that button. Once I turned this function back to its original state of "AF-Lock" as opposed to "AF-ON", it worked fine.
My symptoms were: • soft mechanical noise when holding the shutter (i thought it was trying to focus but couldn't. I thought the mechanics for the AF were faulty) • Couldn't take photos unless they were in the set conditions (which makes sense because it was locked on a certain setting until I pressed the AF-ON button).
My camera is only a few months old so I wasn't convinced it was faulty/broken. Make sure you test all of your settings and go through each of them before you chalk it down to equipment error.
Hope this helps.

Focus modes


There are four focus modes: S-AF (Single auto focus), C-AF (Continuous auto focus), MF (Manual Focus), and S-AF/MF (Simultaneous mode). (SINGLE Auto Focus): Focusing is performed once when the shutter button is pressed halfway. C-AF (CONTINUOUS Auto Focus): The camera repeats focusing while the shutter button is pressed halfway. (MANUAL FOCUS): The function allows you to manually focus on any subject while looking through the viewfinder. SIMULTANEOUS USE of S-AF mode and MF mode: You can fine-adjust focus manually by turning the focus ring after AF is performed in the S-AF mode.
