The EOS M6, Canon's mirrorless model to replace its middle-child M3, is for the same people that all the other entry-level mirrorless folks are targeting: people who want something with the same photo quality as a cheap-ish dSLR to supplement their phone. So the company stripped the viewfinder off its M5 -- it's an option on the M6 -- and redesigned the body a bit.
This cut-price version of Canon's flagship mirrorless should probably be a little cheaper.
