Autofocus I have a nikon d40 with a 18-55 lens for almost a week. Suddenly the autofocus function started to slow down and the noise has changed. I am worried that the AF function will go away permanently.

Take the camera back to the shop where you bought it. It's still under warranty, you should get a new one. It sounds defective.

Autofocus problem


Does this problem still exist when you have the shutter pressed halfway down?

Autofocus on Nikon d90 doesn't work well.


Remember, autofocus needs a difference in contrast to lock on to a subject. It's hard to focus on a solid color so move your camera slightly to find something better to focus on.

Automatic focus not working


The D40x only autofocuses with the latest AF-S (and old professional AF-I) lenses. Most traditional (screw-type) AF lenses from 1986 through today will not autofocus on the D40x. If your lens says "AF-S," you're fine.
Most lenses sold today for the D40x are AF-S, and so is the included 18-55mm kit lens. Many non-Nikon lenses from Tamron, Tokina, Quantaray, Sigma and anyone other than Nikon still won't autofocus on the D40x. Try before you buy, but honestly, there isn't much the included 18-55mm lens won't do.
Autofocus systems are fast, but not usually instantaneous. You have to hold the shutter down halfway as you compose the first shot so the AF system can focus and lock, and then the camera fires instantaneously when you press the shutter the rest of the way. See Preventing Shutter Delay for more.

Nikkor 70-300 lens wont autofocus on d60.. HELP!!!


There is a known defect in some of the Nikkor lens' that were manufactured during a certain time period. The same thing happened to my lens.. it stopped autofocusing for no reason at all. (It was purchased in May 08). I shipped it to Nikon and I received a new lens within 10 days of shipment. You have a 3 year warranty on the camera and the lens'. Nikon has AMAZING customer support when it comes to legitimate issues.
Go to the web site. Fill out a repair order and send the lens to them exactly as stated in the instructions. You will have a new lens within 2 weeks.

Nikin D50 autofocus


I figured out that when changing lenses my finger must have hit the little switch and flipped it over to manual focus. I changed it back and it now works. Thanks.

In the dark


Hey yorkshireboy,
If the viewfinder is dark the only cause of this could be the aperture is stopped down to a smaller opening, which is probably an indication that your lens is not working properly. One way to tell for sure is to bring the camera to a retail location and try out a brand new lens on it, and if the problem persists then your lens is probably fine and the problem is in the camera body. On the front of this camera is a button that stops the aperture on the lens down so the photographer can preview the depth of field, and if this function is broken somehow it might be stopping the aperture down at all times which might be causing your problem. Either way this is a nice camera and I would have the camera or the lens (whichever ends up being the culprit) looked at by an authorized service technician. If the problem is the lens and the lens is a Nikon lens it most likely has a 5 year manufacturer warranty on it and the repair would probably be free of charge. I hope this helps!

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.

Nikon d40 autofocus


This happened to me once on a D70... When mounting the lens, make sure it clicks in all the way when turning counterclockwise. Also it may be worthy to note that both the lens AND the camera must be set to autofocus mode ("A" switch set on both lens and cam).
