>>2635620>it's a fairly popular systemNo, it isn't. And that's why they haven't.
Compare the sales of Canon DSLRs against the sales of m4/3 cameras.
Also, designing lenses for DSLRs, they can do the design once, and adapt it minimally to fit Canon, Nikon, Sony, and Pentax. To simply adapt the same lens to M4/3 would leave you with a huge expensive lend with an enormous flange distance, and a ton of wasted light. So they'd have to start fresh with a new design to make it appealing to the m4/3 user base. If they're going to do that, they're going to work on APS-C mirrorless long before starting with m4/3.
