Overview
This is an in-depth review of the Canon EOS M camera that came out on July 23, 2012, the first mirrorless interchangeable-lens camera from Canon. Along with the EOS M, Canon also announced the first two lenses for the new “EF-M” mount: Canon EF-M 18-55mm f/3.5-5.6 IS STM and Canon EF-M 22mm f/2 STM. Among major camera manufacturers, Canon was the last to enter the mirrorless market. Aside from Panasonic and Olympus sharing the same Micro Four Thirds sensor and Nikon going with a smaller “CX” sensor, all other manufacturers chose large APS-C sized sensors (Samsung, Sony, Fuji and Pentax), each with its own proprietary lens mount. With the introduction of the EOS M system, Canon has officially joined the APS-C club. Instead of developing a new sensor format, Canon chose to reuse the same 18 MP sensor from the EOS Rebel 650D / T4i DSLR camera. Canon also released an EF-M to EF / EF-S adapter for mounting existing and future DSLR lenses on the EOS M, with full compatibility with all lens functions such as autofocus and image stabilization. In this review, I will go over the features and capabilities of the camera and compare it to other mirrorless options, including Nikon 1, Sony NEX series and Olympus OM-D E-M5.
