Pro-level mirrorless cameras have been Sony’s game for years, but now Canon has come to play with the EOS R, a full-frame entry into the future of slimmer, more powerful cameras.

Canon has put out mirrorless cameras before with the M line, which had a smaller APS-C sensor, but the EOS R is its first with a full frame, 30-megapixel CMOS sensor. It also has a brand-new RF lens mount to go with it. All of these lenses have a control ring on them that can be customized to settings such as ISO, shutter speed, aperture, and more. But instead of having image stabilization integrated into the camera, like Sony, Canon builds stabilization into the lenses themselves.
