Sigma Art Lenses Coming to Sony E-Mount->DSLR lens to MILC w/o adapter possible?

Instead of going short flange Canon should just put a 42mm sensor in the EF mount.
Even if they can match Sony’s noise performance in the near future, “eventually” this will all come down to sensor size.
The EF mount is nearly as big as some Medium Format mounts, it’s destined to get a bigger sensor someday, they may as well make that sooner than later.

the lenses now integrate the adapter and all its electronics (sigma mc11) in the body, which is something canon can definitely do to have a basic lineup of popular zoom lenses at the launch of their mirrorless FF
It is irrational to make the lens this way - two CPUs and translating signals.
It is definitely only one CPU with Sony communication signals and the prolonging flange distance is done by simple tube.

of course there aren't simply sigma lenses for canon with built in adapter :)))
my point was that sigma integrated the physical adapter into the lens itself and adjusted the electronics
so regarding the size aspect, the lenses are the normal ones sigma makes with extended mount part, same as samyang does

What's the point of this? you won't be able to use EF lenses to cover the full frame of the sensor, you might as well start with an entirely new mount.

Noise performance is only one issue. Speed is another, and going medium gives a big hit on this.
