With the recent announcement of the Canon EOS R, there has been a lot of people wondering what will become of the EOS M system. As we know, the biggest drawback to the system now appears to be the mount, as there's no upgrade path for EF-M lenses to work on the new EOS R system.
We believe that EOS M will be discontinued someday in the distant future, so don't worry about the system going away any time soon. The EOS M system is not like Nikon's V system, as we believe sales of the EOS M50, EOS M6 and EOS M5 have been very good for Canon. So good in fact that they've powered Canon to the top of mirrorless sales categories in some countries.
We're told that at least two new EOS M cameras will hit the market in the first half of 2019. One of them will be a replacement for the EOS M5 and include 4K with DPAF. We're also told that there will be “minimal” crop for 4K video on the new image sensor inside the EOS M5. So look for the EOS M5 Mark II to improve on some perceived weaknesses in the EOS M50.
No new interesting EF-M lenses have been mentioned since we started hearing about the EF-M 32mm f/1.4 STM. We suspect we'll see updated “kit” lenses when these new EOS M cameras are announced.
