Reflex Camera (Jalen Ransome)


The single-lens reflex 35 mm camera is the choice of many serious amateur as well as professional photographers because the light from the object reflects from a mirror and is taken through the eyepiece to the eye of the photographer, in contrast to a viewfinder camera where the photographer is looking through a separate lens at the subject. The advantage of the SLR is that the eye sees approximately what the film will record, so that you can freely interchange lenses, use close-up lenses, etc. and still see what you will record on the film
