Dear Experts, I accidentally dropped my camera with the lens attached. Now, I'm discovering the auto focus is no longer working. Any idea how to fix it? Is it worth fixing? To repair, where can I send it to? Thank you.

I'm sorry for this misfortune.  Do you normally carry your camera without a form of retention?  Wrist strap, neck strap, sling or other?

This is going to be the takeaway for this camera or the next.  

Start by registering your camera and lens in your MyCanon acct.  

MyCanon 

There you will be given your support options.  If applicable, start a repair request.  Provide as much details as possible.  You will be provided an initial repair estimate.  Package and ship your camera and lens if both were dropped.

It's Canon EF 24-70mm F/2.8 USM L II. It came out the same year Canon release the 5Ds.

Manual focus still work and picture is still sharp. However, the autofocus does not work at all. Curious how much it would cost to fix it. Thank you

 

I take great care of my equipments. It was an accident the camera got dropped out of the storage bag and failed to the ground. The camera bag was on the couch when the camera fell out with the lens still attached.

The lens in question is Canon EF 24-70mm F/2.8 L II USM. As stated, there is no physical damage to the lens that I can tell. Manual focusing works and picture is laser sharp. It's only the autofocus is not working. I know it's not the camera because autofocus is working on my other lenses. Thank you.

Have you checked the AF/MF Switch on the lens. Make sure its set to AF and look at the aperture set make sure it says a number like F/8. Not F/00 or F/-- this means the lens is NOT communicating with the camera. Also what camera are you using this lens on.

Yes. I can confirm the AF/MF switch is set to AF and the aperture is set to whatever aperture I selected. Even when in full auto mode, ISO automatically changes based on the lighting condition.

I am using Canon 5Ds.

 

Thank you.

Does the camera reflect the that the lens is set to AF by saying One Shot, AI Servo & AI Focus. Or does it say MF only on the camera. Have you tried both Live View and Viewfinder to see if it will AF.

Will it AF in live view or vice versa depending on which you're having the issue.
