Sony applied for a patent for a translucent mirror in a camera without a viewfinder. According to the patent’s summary, the composition will be done through the LCD display:
“In recent single-lens reflex digital cameras, a display such as a liquid crystal display (LCD) panel is disposed on the back of a camera body such that an image inputted to an image pickup device can be viewed using the display. For example, there has been proposed a single-lens reflex digital camera, having no optical viewfinder, that allows a user to take photographs while the user checks an image using a display disposed on the back of a camera body.”
