Unlike a DSLR, which uses a mirror to reflect light into a viewfinder, mirrorless cameras – sometimes known as compact system cameras – do not contain a mirror or an optical viewfinder, which makes them generally smaller than DSLRs.

Where space is at an absolute premium, the Canon EOS M mirrorless range offers flexibility and convenience with high image quality in both movies and stills. It uses an electronic viewfinder which saves size and weight but offer extra creative benefits.
