There is a solution to this though. It is basically to turn off the live view display. It took me a while to find this one. The main reason is that I did not know what the option was called. I kept trying to adjust the monitor brightness. But this did not help at all. It was still dark, just not quite as dark. The live view display setting is under the gear menus in menu 2. You simply select the menu option and then you have the option of having it on or off. Just turn it off and you will be set. Now the camera will display a nice bright image on the screen and in the EVF even when you crank down on the shutter speed and lower the ISO. Now you can use the external flash to your hearts content. This will be the same setting for both if you are using a manual flash on camera, or a trigger on your camera to trigger off camera flash units. Now it will work just like a DSLR.
