Question about Nikon D40x Digital Camera

Nikon D40 will not take pictures when in autofocus mode

I have a Nikon D40 that is less than 6 mos old. It will not let me take pictures when it is in the autofocus mode. When I try to take a picture, it will not stop trying to focus. There have been a couple of times that it has taken a picture when the lens is fullly extended, but not always. There is plenty of light, and it takes pictures fine in manual mode. I have changed the battery, taken the lens off, and put it back on, taken the memory card out and put it back in. I've completely reset it, and it still will not work. I just got it to work, but I have to push the AE-L AF-L button while I am taking the picture. Can you give me some advice on what to try, or what could possibly be wrong? Thank you.

I had a similar problem recently with my D-40 and the 18-135 Nikkor zoom lens. When I put the kit lens back on, it worked fine so it turned out to be a problem with the lens. I took it back to the store and since it is less than a year old they are sending it back to Nikon to be repaired.

Is the Tamron AF08N700 auto focus with the D90?


Good morning. You have likely already gotten an answer to this, but yes, it will.

Unlike less expensive models such as the D40, D60, D3000 and D5000, the D90 has a built in autofocus motor, which means that all Nikon F-mount autofocus-lenses (except two for the rare Nikon F3AF) can be used in autofocus mode for all newer generation autofocus lenses like the Tamron 200-800. However, you may want to look around a bit, as Tamron has come out with a new 150-600 lens that is simply terrific (I know, I own one) and the Big Sig from Sigma is equally great.

FYI

Good luck.

Bought a Sigma DG 70-300mm 1:4-5.6 autofocus for my Nikon D40. When the lens is attached the settings get locked on MF. Is there anything I need to adjust to fix this problem? Charles


The Sigma 70-300mm f/4-5.6 DG will not autofocus with the D40 since the lens does not feature an internal focusing motor (HSM). The D40 does not have an AF motor in the body and hence it can autofocus only with lenses featuring an integrated motor (eg. Nikon AF-S lenses, Sigma HSM lenses, Tokina DX II series etc). Unfortunately you can use the said lens only in MF mode.

Nikon D40 will not autofucus.


Check if the swithch on to your left on the lens set to 'A'. If it is set to M this will be in manual mode and autofocus does not take place.
If this doesn't help, try removing the lens and re-fixing it firmly and properly.
Trust this helps.

Will my quantaray tech-10 NF AF zoom lens (for me


Yes, with caveats. The autofocus won't work on D40/D60/D3000/D5000. The metering may not work in all modes on all cameras. Since you didn't specify which camera, I can't give you a better answer than that.

I have 30-year-old Nikon lenses working fine on my D90, but without metering. And the old lenses date before the invention of autofocus.

Autofocus will not work,


Camera wont let you take a picture until focus is locked, why are you using M (manual focus) if you expect autofocus to do it for you? In M mode it is up to you to focus correctly or camera will not take the picture.

When the camera is in auto focus mode, it will not take the picture until it locks onto a subject. If there is not enough light, the camera will "hunt" for something to focus on. Since it can't define any edges, it won't allow the shutter to release.

The D40 base model does NOT have a powered focus lever for autofocus, so if the autofocus is not working, suspect the lens.

No pictures when in autofocus mode


I was having the same problem with my D40... but I read your post, tried switching the 18-55 lens to manual, then back to auto, and it seems to be working fine now. Hmmmm... think maybe there's a circuitry issue with the lens?
