The autofocus stopped working on this lens. Can it be fixed and if so, do you know how much it might cost?

You would do best by bringing the lens to a camera repair facility for an inspection and repair estimate.

Hi, i have the Sigma 70-200mm for Canon EF and the manual focus don't work. The HSM works fine and focuses perfect, but if you choose MF, you can't rotate the focus-ring. Many greetings from Germany! Kai

Hi, not sure if you still have this issue. I have just decided to look into it again, as I had a lot of focus problems with my Sigma 70-200mm HSM lens. Since there is no Sigma support here in Beijing, I took a look - and fixed it.

Here is what I did: On the front of the lens barrel is the rubberised focus ring. This can be removed (gently ply it away from the barrel by sticking a flat bit (or plastic letter opener) between the barrel and the rubber grip. It will come not entirely loose, so you need to work your way around the lens. Keep doing that until you moved it about half way forward. At this point two fixing screws become accessible on the barrel below.

In my case, one of the screws had come loose and that blocked the focus ring from turning, as the screw was blocking rotation in the access hole on the barrel.

Hope this helps others. Simple to fix, if you know how.

I just purchased the Nikon 18-200mm F/3.5-5.6 G ED-IF AF-S VR DX lens for my Nikon D40 on-line for a used camera store. I received it today and I don't think it works, but I wasn't sure. The zoom will...

You are correct. The lens is faulty and there's nothing you can do to fix it as it needs professional attention. Contact the seller immediately to try and get a return authorisation and refund.

Nikkor 18-200mm VR lens does not autofocus any more. Has worked fine but suddenly stopped working. Please help?

Hello. First of all be sure that the lens and the camera are set to autofocus. If that doesn't solve the problem for you, turn on the camera, go into the menu and find the reset function. Reset the camera, what this will do is simply take the camera to all of the factory settings it had when it was new out of the box. J.

My Sigma apo 70-200mm f/2.8 hsm lens functions fine. Focus works and zooms just fine. The problem is the front part of the lens is loose. You have to hold it to secure it while shooting. Otherwise you can...

Am having the same problem. I fixed it once but can't remember how I did it. I think there are screws under the mounting ring -which has four screws itself. Then, I think under the green computer board, there are other screws that should be tightened... I will look at mine tomorrow and come back here to report.

Lens is moving

It is not normal. Something may have loosened up internally. Set the lens to 50mm and then move the camera between pointing lens forward and lens down toward the floor as the camera might rest when you have it on a neck strap and bend over. I am guessing that gravity is pulling the lens out to the 200mm position. In any case, you should have a camera repair man look at it. I do not know what the repair could cost, but you have a superb lens and, if necessary, you may want to spend the money to fix it.
