The Verge about the 3rd iteration of the Sony RX100:
But there’s another equally impressive feature that’s hidden inside the camera when you first pick it up: a retractable electronic viewfinder. Sony seems to have pulled off a masterful feat of engineering here. All it takes is the flick of a button when you want to call upon the high-res, 1.4-million-dot EVF. Then once you’re done, it simply disappears back into the body. A retractable EVF on a camera that fits in your pocket. Color us impressed.
