You have it listed as an AF lens. Why won't it autofocus?

On your camera you must adjust the aperture ring all the way to f/22 , if not it will not auto focus .My lens works well with Nikon 5000, D90 on both manual and auto focus . Remember the aperture ring must click to the f/22 spot on the aperture ring . Good luck Michael lomax .

Depending on the type of camera you have. "Lower" consumer models will not focus such as the D3000 or D5000 series. The lens has a screw drive focusing system that is meant for the camera body to focus the lens. The newer camera lenses use internal focusing systems on the lens and are communicated to do so from the electronic connections between the lens and camera.

You have to have a NIkon DSLR with a built in screw motor for the autofocus. Nikons with autofocus motor in body: D50, D70, D80, D90, D100, D200, D300, D7000, D7100, all pro models (D1, D2, D2, D3, D4, DF, D800, D810). Models derived from those (D300s, D3x, etc.) also have AF motors.Nikons without AF motors: D40, D60, D3000, D3100, D3200, D3300, D5000, D5100, D5200, D5300.

You need to check the specs of your camera to make sure that this lens is ok.for example: D7100 is ok but not D3100.

it doesn't have an internal motor so needs to be mounted on a camera that does.it won't auto focus with the D3xxx and D5xxx cameras.

You have to have a nikon camera with a focusing motor to auto focus with this lense.Make sure the lens is set and locked at f 22. Hope this helps.

It's working fine with the autofocus mode on your lens, would also work with the manual focus but you would have to preset the focus on the lens.Michael

I just figured out how to do this today with my new lens. Since Sigma did not put the autofocus/manual focus switch on the lens itself, you need to go into the information menu (the i menu on the lower left side of the camera) and set your focus mode to manual (change the AF-A on the right side to MF). Once you override the autofocus on the camera, use the outer ring on the lens to focus. Hope this helps! Took me a little bit of research to find this. :)

Christina: Your camera will not autofocus with an AF lens, as it does not contain the motor inside the camera. (SWM), but will perform all other functions manually. You need AF-S lenses which contain SWM motor. That is why the difference in price from an AF-S and an FS only. I hope this might help.

I have the gf3 and mine will say that if I have it on autofocus. Put the focus in manual and click away after getting the focus, shutter, iso etc how you want for your photo. Fun lil lens. Ive gotten some great shots with this.

I just received one of these today. There is no autofocus on the D60 for this lens, so you have to set it on M. Also, if you want the aperature to be set by the camera, you must lock the aperature setting ring. I've only been playing with it for a few minutes, but I've noticed you cannot always open the aperature to f/2.8 using the camera controls; sometimes only f3.3.

J Gibson:I dropped my old 50mm 1.8D and this is the message I got after that, I had to replace it. It might be a defective or broken lens. I would suggest trying it on another Nikon AF camera and if it still doesn't work hopefully you can return it or have it replaced under warranty.

I second guessed myself as well in the beginning. The lens has a pretty long manual throw. i.e. it takes some big turns to get things into focus manually. Keep trying and it should eventually get things into focus.

Hello, there is an Auto Focus on this lens. Click the switch by AF - M to use Auto Focus (AF) however when shooting Macro, it's usually better and easier to manually focus. I hope this helped.

Cheryl - some time ago I bought a "slightly used" lens from an Amazon vendor. It would not autofocus in live mode on my Nikon D5100. For some time I thought this was a problem between the camera and lens, but I finally consulted Tamron and they said it would need expensive repair. Amazon was gracious let me return the lens. In manual focus it took wonderful shots - but I have no way of knowing if you are talking about this same particular lens.

Even in Manual mode you'll have to switch the Auto Focus from AF to MF (Manual Focus). It's a separate menu option not connected to the Manual Mode function. Does the lens still try to autofocus when you depress the shutter button? If so, you still need to switch to MF mode.

This lens doesn't attach to the camera. It works like a filter, attaching to the end of the installed lens. If the main lens you have installed works with the autofocus this lens will too.

If you have certain lenses the focus ring pulls forward and back to enable Manual focus - if you can see a distance scale on the lens , you are in MF. And you might think AF doesn't work - just push the focus ring forward to get into AF

My experience with adapters so far is the autofocus has not worked. Your camera is totally manual

Had the same issue with a Nikon d5100, but after a few tries it was resolved. Check the following:1- for some reason, the lens didn't fit in with the camera, but after trying a couple of times it finally clicked into position2- there is a ring near the lens (the left part of the product picture) that must be slide out for the lens to autofocus. After you slide it you'll see the AF appear from under the ring, beore that there is only MF ( manual focus) visibleAfter these two the lens worked perfectlyHope it helps

It will not autofocus. If you purchase this lens you will have to manually focus all of your shots

The inner workings of this lens and that camera are different, so it will not autofocus.
