Jean, thank you for this - she is a beautiful young woman! I'm completely ignorant about studio photography but I know there are plenty here who have experience and hope that they'll get a chance to see this over the next days.
This is correct, the EP-2 is not good for studio. In this case diaphragm was shut down to f8. (manual mode) so the screen is very dark and difficult to compose.
I could not use the viewfinder because the radio trigger was in the flash socket.
