Canon EOS (EF-M)
Canon EOS M is the first mirrorless interchangeable-lens camera produced by Canon.
DPReview noted that the EOS M is effectively a miniature version of the Canon EOS 650D, which was introduced in June 2012, with a simpler physical interface. The letter M in EOS M stands for "mobility" and EOS means "electro-optical system".
It was replaced by the Canon EOS M2 in late 2013.
