Autofocus does not work ( when ON ) with any lenses .

Posted by on

  • krazydarcy Jul 17, 2008

    My autofocus seems to sweep from far focus to near and back once and gives up trying to focus. My focus indicater when in manual focus ) works fine which tells meit's not a problem with the sensor. I suspect my problem might be the firmware (flashed from v1.0 to 1.02)

I remember reading a review of the K100D that mentioned that it had poor low light performance. I know mine has a really hard time focusing in low light situations. It does the sweeping back and forth & most of the time never ends up taking a picture. (Even when it bursts the flash to try to focus.)

I've just started experimenting by using a flash light aimed at the subject I want to focus in low light situations, and the camera seems to be able to focus & take a shot more reliably.

If this works, I'm going to rig up something to hold the flash light underneath the camera so that I can use it more often.

I will post an update if this works!

Take Care & Happy Imaging!

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.

Operating nikkor 70-300mm f4.5-f5.6 with nikon d5100


No Nikon lens ever zooms automatically, so I assume you mean focus.
The D5100 lacks an autofocus motor, requiring the lens to have one. The older 70-300mm lenses lack this motor, expecting the camera body to have one.
The D5100 will only autofocus with lenses designated AF-S or AF-I. It will not autofocus with older AF-D and AF-G lenses.

Autofocus Lens for Nikon 70-300 1:4-5.6 AF25-166-4553 is mountable on a D3100?


You didn't specify the make of the lens. Assuming the lens has a Nikon mount then yes, it will mount on a D3100. The big question is whether it will autofocus on the D3100. The D3100 does not have an autofocus motor, relying on the lens to have one. Not all lenses do. Nikon designates lenses with an autofocus motor as AF-S. Other manufacturers use different designations.
If you need further assistance, feel free to reply to this post and give the make of the lens.

Was told by amazon that your 50mmF2.8 DG macro would autofocus on my nikon d40x...it does not...am I missing something or did amazon mislead me? Thanks Kevin


FixYa does not make lenses. From the name, I'm going to assume it's a Sigma lens.

The Nikon D40x does not have an autofocus motor, relying on the lens to have one. This particular Sigma lens does not have such a motor. Sigma designates their lenses with an autofocus motor as "HSM", Nikon calls theirs "AF-S".

I saw nothing on Amazon's page for this lens specifically mentioning the D40x. If someone there told you that it will autofocus on the D40x, then yes, you were misled.

I have a Nikon D60 and my autofocus has stopped working. It is not because of the lense because i have tried other lenses and the auto focus won't work with them either so it must be an issue with the...


You should check custom menu setting 2, and make sure it's set to one of the auto modes. Make sure the lenses you are using are AF-S and not regular AF lenses. The D60 has no autofocus motor, so autofocus only works with AF-S lenses.

I always suggest folks take a look at Ken Rockwell's website also, here's a link to a specific page on autofocus on the D60.

Post a comment here if none of this works and I'll see what else we can do.

D90 won't autofocus at distance


Mine seems fine. The only other thing I would think to check is the focus lock is off and the focus area setting.

Won't take pictures when set to A on the lense.


if you're using D40/X, make sure that the attached lens has built-in autofocus motor (e.g. code AF-S for Nikon, HSM for Sigma), because the camera does not have built-in autofocus motor in the body so only manual mode will work in most AF lenses..

if you're lens is already one with built-in autofocus motor, you might need to check the motor at a service center

Try you 18-200 lens on another Nikon DSLR. If it still does not Autofocus. It is the lens. Sometimes the electrical contact points of the lens are not making correct contact with the camera. ok?

Nikkor lense


You need AF-S or AF-I Lenses. These have the autofocus motor built in to the lense. The D40 and D40x does not have an autofocus motor in the camera body itself, while the D80, D300, D3 Etc to have the motor in the camera. You can use most old lenses on your D40x, but you will have to focus them manually.

See Ken Rockwells page for a lot of D40 / D40x info
