Problems tethering 5D Mark IV to Canon Utility 3


Before I shot with a 5D Mark II it was tethered to Canon Utility 2.  The image was saved to the a folder that was watched by LR.  LR imported any image in the Watched Folder.  This allowed me to transfer just a jpeg to the laptop as being tethered to directly to LR would only transfer a RAW file.  Not super fast but worked fine for my needs.


Then, about a year ago,  I bought a 5D Mark IV and tethered it using Canon Utility 3.  I've had nothing but problems.  It works for awhile and then the camera locks up.  It will not shoot.  The viewfinder says "Busy".  At first, I could disconnect the cable (the one provided with the camera) and connect it back and it would continue shooting. But now that is not working. It's become such a problem I can no longer shoot tethered. 


I can't think of anything that I'm doing differently from the Mark II.


Any ideas?



Hello pcather, 


  • You can control the camera remotely from EOS Utility Ver.3.x, and by viewing the subject in the EOS Utility Ver.3.x window, you can set the camera and shoot. You can also shoot by directly operating your camera even during remote shooting, or preset a time allowing the camera to shoot automatically with timer shooting.
  • For information on how to connect the camera with the computer, please see the "Related information" section.
