iStopmotion 3.1.1, OSX 10.8.4 and Canon 5D mkiii don't work

Hi, I’m trying to use Istopmotion 3.1.1, OSX 10.8.4 and Canon 5D mkiii, but I don’t see any preview and also when I take a photo the software blocks my camera and I must turn the camera off and I must take out the battery and all my cards. Any solution?

Unfortunately iStopMotion 3.1.1 don’t show a live feed from still cameras. However you should be able to work with the Canon 5D Mark 3 according to our list of user tested devices:

iStopMotion isn’t talking to the camera directly, we rather ask MacOS-X to get an image from the connected device and MacOS-X is taking care of the communication. If the camera refuses to work after MacOS-X has requested to capture an image this leased to my assumption that this communication is broken.

Did you have put in a memory card where the camera can store the image onto? Did you switch off the auto focus?
