sigma native fe mount vs mc-11

[domart]

does anyone have any hands on experience into whether the native mount sigma art lenses actually fare any better than canon mount on the mc-11, I would happily trade in my entire stock of canon mounts if they do, but for some reason I just assume that the performance would be identical

No the performance of native lenses are lot better infact as good as any Sony native lens for stills. The video AF is not as good as native Sony lenses but then it's not that great with MC-11 anyway. For stills it's nearly as good as native lenses.
Also I hear FE native sigma ART lenses supposedly weathersealed too unlike DSLR versions and mc-11
