Hi,
My Sigma lens has stopped working in AF mode. When i push shutter button nothing happens. Any Suggestions.
i have checked that the AF switch is on on the lens and that the camera is not in Manual mode. I have read that these lenses are prone to motor burnout.

The first thing i did after checking my settings was to change my battery even though the battery in it was fully charged as i was all set to take loads of photos of the Jersey Battle Of Britain Air Display. Ended up not taking any as faffing about trying to fathom out problem. Good job we had a view from home and not had to pay

As Umberto has already linked you to my experience, all I will say is I think you will probably find Sigma to be sympathetic.

How old is the lens ? If it is out of warranty then you can see their fixed tariff for repairs HERE I think your lens will come under Tariff 4

Good luck, you should get a reply from Sigma in your mail tomorrow.
What camera is it? Some cameras have AF/MF switches on bodies & lenses. Check them first, may have been caught!

I don't mean to sound patronising but the most common solution is the easiest one!
