most Basic SLR (Single Refraction Lens) Cameras use a single lens, however MOST advanced SLRS use multiple Lenses.
it is best to use Multiple Lenses because a single lens can sometimes be bad for Wide-Angle shots, and when you take Macro (super close) images your restricted to a certain distance from the object, though the down fall on Multiple lenses is that it cam be more expensive then single lenses
or if you meant only being able to use one lens at once, that isn't true, many Lenses can have add ons for example my Miranda FvT (yeah its old) can use multiple lenses, for Macro i use the Macro Tubes with a 2X Custom Tele-Converter Vivitar lens with the standard Soligor Wide-Auto lens, and so on
