Question about Tamron AF 28-80mm Lens

1 Answer

Auto Focus stopped functioning and there is no AF point display

I have been enjoying this lens for a couple of years now with my Canon Rebel XT. Last time I tried to used it however, no AF Point display will appear on camera and the autofocus does not work at all. I know it is not the camera because when I switched to another lens, everything functioned as expected. And yes, I did check the slide control on the lens if it is on AF and not MF.

Thanks!

Could be that the electrical contacts on the lens / body need gentle cleaning - try that.

Nothing you can do. The Tamron is not compatable with your camera. So the focus will be slower

Make sure the lens is set for the largest f number on the aperture ring. there may be a lock to prevent the ring from turning in the future. Locking the lens of the largest f number allow the camera to set the lens through the camera. This is normal on most of the newer cameras.

If the lens does not have a move-able aperture ring, then dismount and remount the lens, making sure the lens is completely mounted and locks into place, completely lining up the contacts inside. If this does not work The camera or lens may need servicing.

SOURCE: The auto focus does not

Hi, It wouldn't autofocus on the D5000 as the body doesn't have an auto focus motor in the body and since that lens is AF, not AF-S, it won't autofocus. It should autofocus on the D7000 though, how far away are you from the object you're trying to photograph?

Will not auto focus with a smaller lens.


I had the same issue with my Nikon d60...my 18-55mm did auto focus but my 55-200mm only manual focused, i thought it might have been my camera as i heard that not all lenses are compatible with my d60 but it turned out to be the focussing motor or something that was damaged, it was making a very funny noise when it tried to auto focus with it,like a screeching sound..if this is the case you should get it repaired and looked at, also check on the lens if it says it is a AF lens,if so make sure th switch on the side of the lens is switched on AF not MF. hope it helps

cheers

No AF point display indicator in Creative Zone modes.


In creative mode I would imagine that you are required to choose the focus point. Try the arrow buttons.

If it's an older lens, for EOS film cameras, Quantaray might upgrade it free - contact your local Ritz Camera store ( it's imported by Ritz ) or find a repair center for Quantaray online.

I bought digital Canon EOS Rebel XT two years ago, and I have really big problem with AF. I got one half of the pictures fuzzy. Sometimes the green light is on, I took the picture and it is fuzzy. Next...


Is the lens on AF mode?

Have you tried more than one lens to determine whether it's the lens or the camera itself?

You may want to have lens calibrated. Send in for service?

Autofocus jumps around and often will not settle on the correct setting


what i do is usually put it onto manual focus then back to auto focus, what it may be is that you are using the wrong lens for your subject :/

Automatic Function will not work!!


I had the same problem a few moths ago when I tried to use a Quanta lens. Go into the second tools menu, select clear settings, then select Clear all Custom Functions. It worked for me I hope it works for you.
