New Canon 50mm f/1.4 – an EF-mount Defocus Smoothing lens?

One of the most intriguing optics on the Canon RF lens roadmap is the Canon RF 85mm f/1.2L USM DS – the DS standing for 'Defocus Smoothing'. Now it looks like Canon is working on a DS lens for its EF-mount system, thanks to a patent for a new EF 50mm f/1.4 optic. 

So what is a Defocus Smoothing lens? A spiritual successor to Canon's earlier Softfocus lens, Canon's Product Intelligence Consultant, David Parry, explained it thusly: "Using different lens elements, it will give a different look to foreground and background blur and a much smoother look to the bokeh effect. And that will change with aperture as well, so you'll be able to get different degrees of effect on that depending on what aperture you're using."
