It's probably broke then. Clean the contacts to the camera and try again. If it still don't work you can probably be sure it is likely to be a bit faulty. Check the camera has auto focus mode enabled if appropriate.

Auto focus will not work on my canon 40d


First of all you need to clean the connectors on both the lens and the camera. Do this by using a pencil eraser being careful not to get bits in the camera or lens. If this doesn't clear the problem is it that auto focus doesn't function with any lens. If that is so then you need a camera repair. If auto focus is only non functional on the Sigma 170-500mm and you can manual focus then the probable problem may be a broken ribbon cable in the lens itself. This will need to be replaced. Usually a quick and relatively cheap job.

Won't auto focus


Make sure the auto-manual focus switch on your camera is set to auto (A) and also make sure the auto manual focus selector on the lens is in auto (A) as well. If your lens contacts are dirty then this will affect the function of the lens as well. Clean those with either a lint free type cloth and alcohol or methylated spirits.

Can I use my Quantaray 28-80mm lens with a new Nikon D3000?


Quantaray makes their lenses available for a variety of camera brands. If the lens has a Canon mount, then no. If the lens has a Nikon mount, then yes.

Also, bear in mind that if the lens does not have an internal focusing motor then you will not get autofocusing with the D3000. Everything else will still work, but you'll just have to focus manually.

IN AUTO FOCUS FOCUS RING STICKS MAKES NOISE LIKE


How new is the lens? In or out of warranty? If out or warranty most likely solution is to find a Sigma authorized repair shop because your description sounds like the auto-focus motor gear has failed. If in warranty, check out Sigmaphoto.com for repair sites and also download the SIGMA_SERVICE_REQUEST.PDF. I've only had to deal with Sigma once on warranty matter and they were very helpful, provided UPS authorization for shipping on their nickel.

Nikon D50 with Nikon DX 18-55 lens will not focus


Hi,
Sorry to hear about your lens. If you are able to autofocus and take pictures with any other lens, then it means that your problem lies with the kit lens. If you can take picture in manual mode, but not in autofocus mode, then the AF motor in the lens in not functioning. I had the same thing happen to my 50mm 1.4 lens.

Depending on your location, there are Nikon repair centers in Melville, NY and Torrance, CA.
Hope this helps,
Andrew

Auto Focus not working for Canon EFS 18-55mm lens


I see this same problem occuring all over the internet on Canon lenses. Autofocus not working any longer. For some stupid reason the lense will lock up and quit autofocus while other lenses will work fine. A light pull on the lense focus ring away from the camera body will give a noticable pop or click which unlocks the jammed lense. Try it if you are having troubles with your autofocus. This is a very common problem and worth giving it a try.

Manual Focussing failure with Canon EF 100-400mm SLR zoom lens


I doubt if there is anything you can do yourself. The manual focus may have debris under the ring or is in need of parts. I would leave this one to a tech.
