It may be focusing on the attached glass make sure its clean and make sure tour camera is in auto mode other than that I have no idea I don't ever remember owning one

I wish I could help you but sadly I can't ! I bought the same lens and it works perfectly well ! It's on my camera (a canon T3 rebel) permanently except when I need my zoom ! Maybe you should try it on another camera ! It would tell you if it has a defect or not ! Sorry about that ! Arnaud.

It may be trying to focus on the glass it self and is not focusing on your shot. make sure it is clean besides that I don't know my wife's doesn't do that.

It screws on to the front of your lens. There are adapters for different lens diameter sizes. Yes it does work in auto - both auto focus and auto shooting mode.

Mine does the same thing. Lens seems to work just fine. Probably has a friction clutch which permits the focus ring to turn past the stops

It automatic mode the camera focuses fine. I haven't tried it in other modes yet, but if you have an autofocus lens I imagine it will focus for you fine.

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. :)

In auto mod it changes. But in the manual mode you select your f and focus manually.

I've tried it once, just once, and the auto focus didn't allow me to do this.

I have these lens and I cannot use the autofocus, only manual. It won't focus no matter at what range. So disappointed..

What do you mean by it doesn't recognize? If you're talking about the aperture control auto focus etc its normal because its a manual lens everything is controled on the lens. dont forget you have to enable the feature "release without Lens" otherwise you can take pictures :)Hope it helps

No, autofocus doesn't work. You have to set the camera to manual mode and manually focus. However, it's not that difficult once you activate the zooming mode to help you focus.

You have to use manual focus with all adapters. Well not all per say but the ones that have electronics for the autofocus cost alot. we are talking 300$

It will not auto focus but it will work. A piece of advice : don't buy it. It is very very bad lens.

I haven't gotten mine yet, but I ordered it. I think I read that the silver ring on the front of the lense is how you adjust the focus...give it a try! If it doesn't work, contact the seller or something.

Did the focus lock? Make sure focus sensor is on something it can grab. Try manual focus to test mechanism.

With the LAEA4 auto focus works when used with Alpha lenses. Otherwise you would have to focus manually.
