And yet sony keeps making better, smaller fast lenses than canon. The maximum aperture E mount an support is f0.7, and RF can support f0.68, that's what you get from 1mm of mount lmao.

At some point you are going to have to admit that this has nothing to do with mounts and everything to do with the competence of the engineers and the capital on hand to take risks and invest in tricky shit like making fast glass that is also sharp. NIKON didn't make those fast primes because NIKON's engineers were neither the highest paid or the ones with the access to the most capital, and they are STILL a third rate company. Z mount is perpetually 3 gens behind in everything.

There's no technical reason pic related couldn't be autofocus. The mount bayonet is always the same size. There isn't glass in the way for a screwdrive interface. They could bloat up the barrel to fit a built in motor. Nikon was just incompetent and short on cash like they always have been and continue to be. The actual reason is nikon lacked the talent and funds to develop a sharp autofocus version of this lens that would sell well.

You are just another photographer larping as an engineer because he read some basement chart shooters blog once.
