Keeping your camera steady is no small feat at the best of times, but being forced to hold the camera away from your body to view an image through the LCD adds a new level of instability to the picture-taking process.

If you turn on the back LCD, the electronic viewfinder will remain on while in a shooting mode. There is no setting on the camera to use only the back LCD monitor while shooting. If you playback images in the Play mode, only the LCD monitor will turn on. However, if you press the Monitor button while in the Play mode, than the back LCD monitor will turn off. The image will display only in the viewfinder LCD.
