My Recommendations for a Core Canon Mirrorless System, Some with Deals
See my Nikon mirrorless wishlist.
Following my recommendations for a Nikon mirrorless system, here is my recommendation for a Canon mirrorless system whose lenses rock. The Canon EOS R is a good camera, but only 30 megapixels, but I expect Canon to offer high megapixel camera before long.
The DSLR lenses can be shot on the Canon EOS R with the Canon Mount Adapter EF-EOS R (currently included with the Canon EOS R along with the discount).
At this point the Canon RF lenses below are so impressive that I am not recommended any other lenses yet. The Canon EF 11-24mm f/4L is an excellent lens but I hope an RF version is coming. In the meantime, it covers the wide end superbly.
