Canon join the compact mirrorless camera brigade with the new EOSM.

As a latecomer to the area Canon had to do something a little bit special to stand out in the crowd of excellent compact cameras.

One of the interesting innovations is they use some of the sensor pixels for the Phase Detect autofocus system. These sensors are normally housed in the pentaprism area of the  DSLR viewfinder system. Without a viewfinder many manufacturers relied on the slower Contrast Detection autofocus method for their mirrorless offerings.  With an  18 megapixel sensors Canon had more than enough pixels to use a few for the autofocus system.

To try and reduce the size of the whole package Canon introduced a new compact lens mount, the EOSM. There are two new lenses, a conventional 18-55mm zoom and a 22mm pancake prime.
