Interchangeable lens means it has a capacity to interchange different lenses to shoot photos at different depths of field . MILC is a further evolution phase of SLR cameras in which the optical mirror is replaced with a digital mirror . </P> <P> The biggest difference between mirrorless and DSLR cameras is that electronics take over the mechanical tasks of the' reflex' function . In other words, DSLRs use a mirror - box unit to reflex the picture to an optical viewfinder or digital display . A MILC uses a digital display and does not have an optical viewfinder . MILC use high speed contrast detection auto - focus to do this function, rather than the phase - based auto - focus used in SLR cameras . </P>
