Sony's micro-single is better. Sony and Nikon, which are dominant in high-end mirrorless cameras, just entered the field of mirrorless cameras in 20 18, and their product systems have not yet taken shape. Sony entered the field of professional camera production after acquiring Minolta SLR product line, but later turned to the mirrorless camera market, which Sony called micro-single. Sony is the earliest and most dedicated of the three. After nearly ten years of development, Sony has formed three product lines: high, medium and low.

Canon also entered the no-reverse product earlier. As early as 20 12, Canon has already developed EOS M, which is also a non-inverting model of APS-C, and adopts EF-M bayonet. Canon has also developed a compact and cost-effective EF-M lens for EOS M and subsequent models, which has achieved great success.
