The Canon EOS M10 has been officially discontinued by Canon Japan. Announced in October 2015, the M10 represented the lowest tier of Canon's EOS M series. In August 2017, the EOS M100 was introduced to fill the same role, making the M10's discontinuation inevitable.
B&H still has the Canon EOS M10 in stock, but the M100 is newer and, with the current instant rebates, less expensive.
