 The concept for cameras with live preview largely derives from electronic (video) TV cameras.Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism.The first digital still camera with an LCD for autogain framing live preview was the Casio QV-10 in 1995.
