Although no longer available from new, the Leica M E is a full frame digital camera that takes interchangeable lenses. It doesn't have Live View and a video function, so is purely a camera for taking photographs, which means that all the research and development is from a photographic background. It does have a 2.5" TFT LCD screen, as well as an optical viewfinder and at 18 megapixels produces great detail on each and every photograph.
