Hi folks,

With the announcement on Sigma Art Lenses will be available on Sony E-Mount. Is that mean DSLR lens for Mirrorless without any modification is possible?

Will Canon solved the mount issue?

Cheers~

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

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.

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

The sigma art lenses are big enough on the dslr's. Adding and inch in length to already big lenses for a smaller camera is not something I'm interested in.

I would have loved to see a line up of f2 lenses for the FE mount.

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.

Cameras: 5DSR, A7RII, 5D III, EOS M6/M5/M3, Mavic Pro, DXO One.  Oh, and more lenses than I care to count.
