Markoney why do you think turning off the image preview will help? Mine still does it even after going back to 1.4. I already had my view finder off and on screen only. I could try to turn off the review but I do want that on.
I just upgraded to 1.5 today and it freezes constantly for me as well. It does it almost immediately when I’m using USB controls on the camera to change settings. It doesn’t seem freeze when I’m using it not under usb control
