EF Lens 24-70 mm keeps my 5D Mark IV from turning on

rapadou

When the lens is attached to the camera, this won’t turn on. In order for the camera to turn back on I have to remove the battery and the lens.

Has anyone had this issue with an EF 24-70?

Hi and welcome to the forum:

Have you tried turning the camera on with any other lens and, if so, what was the result?

Hi Tronhard

 

yes I have

Camera works well with wide angle sigma lens

If that is the case, I would suggest that the camera likely does not have the issue, but there is some short in the circuitry of the lens causing the camera to lock up.  Next step is to find another camera that is compatible and put the lens into that it to see if the lens locks it up.

Greetings rapadou,

We agree with the information that Tronhard has been able to provide. If the 24-70mm lens does not work on a different Canon camera body then you may submit a repair request through our online repair portal to see if you could send it to our facility for service.
