Canon last had an EF-M camera and lenses in 1991 (inset, LCD screen pic)
The Canon EOS M mirrorless camera with new EF-M mount and lenses is due to be officially announced on Monday. The EOS M seems to be closest to the Sony NEX C3. The lack of physical controls hint that it is too basic to compete with the NEX 5N or NEX 7.
Because it is designed to work with Canon’s new STM AF lenses which use phase detect AF on the sensor I am 100% certain the EOS M will have the same 18MP APS-C CMOS as the T4i / 650D. Using the G1X sensor would make it incompatible with the very EOS-M lenses it is pictured with at launch. The 18-55mm EF-M STM and 22mm F2 EF-M STM.
Will the new mount be the basis of a C100 affordable digital cinema camera, following the strategy of Panasonic and Sony?
