Canon will manufacture 100,000 of the cameras a month, the company said in a statement.
Mirrorless models have large sensors, providing good picture quality, but no optical viewfinders. That enables manufacturers to keep the camera body smaller and lighter.
In Japan, where consumers tend to value easily portable products, mirrorless cameras account for around a third of all interchangeable lens models. In the United States, their market share is closer to a tenth.
