Ever wonder why Nikon doesn't have f/1.2 AF lenses and Canon does?

Look at the VERY thin parts on the 50mm f/1.2 AI-S.

Parts apparently have to be very, very thin at the mount, including the finger-like part that engages the metering system, and the metal end of the mount, itself, on an f/1.2 lens. Keep in mind that I am not an engineer, just judging by eye. The glass element, too, seems quite vulnerable, as it protrudes from the mount.

"E" lenses would, seemingly, be easier to engineer if built with f/1.2 maximum aperture, but again, I am not an engineer.

I wear a badge and pistol, and make evidentiary images at night, which incorporates elements of portrait, macro, still life, landscape, architecture, and PJ. I enjoy using both Canons and Nikons.
