   It's always meant a camera which uses a single lens for both view   
   finding and capturing image.  That used to be done with a flip mirror   
   between the lens and the film. I assume the word "reflex came from the Z   
   shaped light path and the flip mirror.  Early high end  CCD cameras   
   still use a flip mirror in front of a CCD.  Most designs now use the   
   same CCD both for capturing a video viewfinder image and the the   
   captured image without a flip mirror.  Most also function as video cameras.   
      
   I don't know who made the first SLRs.    Kodak and Nikon were popular   
   the early 1960's when I got interested in photography.   
      
   It obvious advantage of the SLR camera is that it gives the same field   
   and focus to the viewfinder as to the captured image. It may or may not   
   have interchangeable lenses and be called an SLR.
