Before I go install the wrong version and have to re-install the correct one, can someone verify that EOS Utility 3 will work with both the Mark IV and the Mark III bodies? It's not clear to me on the EOS software web site: https://www.usa.canon.com/internet/...O-_-SupportPFLandingGreyBar-_-eos_all#eos-all There is a different version of the utility for the Mark III and the Mark IV (v 2.0 & v 3.0) and I want to get the correct one installed. Thanks!
You want EOS Utility 3.9.0 for Windows not only is that the one for the newer camera but I double checked the software details and it said it supports the Mark III. Even if it didn't you would have to have the newer one to support the newer camera. Worse case scenario you would have to run both the versions of the utility on your computer to support the older camera models.
