Rather than having a seperate viewfinder, an SLR camera used a mirror system to reflect light to the viewfinder, snapping out of view when you want to expose the frame.In the digital world, you generally have a live preview option, along with an optical viewfinder that was slightly off of the actual lens. D-SLR camera (Digital-SLR) generally lacks a realtime LCD preview, since the mirror is in the way, although newer DSLR cameras do offer the ability to offer the traditional preview like a standard digital.
