Is this is really a dead end? Probably yes, but for the past. There was no way out of this impasse at times when cameras were mass-produced. Thorough, over the years, the world has changed a lot, and we have new opportunities. Let’s speculate, maybe it’s still possible to create a universal camera for all types of lenses with a universal linked rangefinder? Maybe, we should forget about the connection between lens and the camera?
