Re: Sigma 14-24mm 2.8 art uneven sharpness

You didn't say if these shots were made using a tripod or other device to lock off the camera.  If these shots weren't done on a tripod, you should reshoot them.

I'm not going to look at them on the crummy laptop I'm currently viewing on, but I have a question:  Could this side-to-side unevenness be caused by the adapter?

Even a very small variation in the evenness of thickness of the adapter can be exaggerated by a super wide lens, way beyond what a 50mm or 200mm will show .
