    Lens stopped working on Autofocus.

    My Nikon 70-300 stopped working on Autofocus last night. I was shooting at my fish tank and suddenly it wouldn't autofocus anymore. Continually trying to focus i can hear it whirling as it tries.

    Any ideas on things i could try? it does work on Manual and other lenses work on the camera.

    Worth fixing or buy a new one?? its my walk about lens, its on my camera 5 days a week and i guess 3-4 years old?

    Any help appreciated.

    Bummer! You could try cleaning the contacts both on the lens and on the camera. Also, flip all the switches to make sure one isn't stuck in between settings. Which 70-300? FX or DX? AF-S or AF-P? Nikonusa has the FX AF-P in their refurbished section, might be worth checking out if you can't get it fixed. Fingers crossed!

    Since you have two cameras, does this lens fail on both cameras? Also, you might give the lens contacts a good cleaning and try again. If the lens fails on both cameras after cleaning the contacts, I would look into a repair estimate and go from there.

    i tried cleaning the contact and the switches do move free. Its the ED G lens which i believe is FX.

    Same result on both cameras.

    Appreciate the replies.

    What comes to my mind is the 70-300mm is no macro lens. Try backing away a couple of feet from that fish tank and try again? No focus limit switch on the lens I know of, so maybe not that. I like Brent's idea of testing lens on another DSLR to verify it is the lens itself. If this is an older example 70-300mm that uses the camera body autofocus motor through the screw-drive on the mount, it would be important to isolate that.

    If it's 3-4 years old, shouldn't it still be under warranty?

    This is a good suggestion. Nikon now lists in its warranty that lenses need to be registered online to obtain the full five years for warranty work. Otherwise, supposedly they only offer one year. Check when you purchased it, and if it falls within the 5 year time frame, go online and register it if it hasn't already been done. Then go through their website to request repair. Providing it is covered under warranty, the only cost should be shipping the lens to Nikon. They pay for the return shipping.
