Once upon a time Canon - heck, all the major makers - made nice rangefinders.
The SLR was born to solve some problems rangefinders had. Today with electronics, one can build a compact that will do macro or somewhat long telephoto work well, where the film rangefinder has issues with this.
Time for full circle, or almost full circle. I doubt we'll see a resurgence of RF cameras but small compacts with EVFs taking small lenses.... sure!
