The mirrorless camera market was long notable for what it lacked: hardware from Nikon and Canon. Technically Canon has had a mirrorless offering for about four years, the EOS M, but it was a low-end model that felt more like a token gesture than a real camera.
Small and light enough to appeal to fans of compacts; Very fast and accurate autofocus---one of the best AFs we've seen; Excellent electronic viewfinder and touchscreen for easy and comfortable compositions
Lacks fast native lenses; There's a lens adaptor, but it costs another $200; Viewfinder blackout is pronounced; No 4K video, which feels odd in 2017
