The corner is much better with 24-70. The corner sharpness is very good with 24-70.

With my copy, I am not impressed with the corner sharpness of the 24-70mm f/4 at all. It seems decent enough by 50mm, but don't think it is much different than the 28-70mm overall. The issue is, my good copy of the 28-70mm I had to send back to return a broken A7, and my current copy is maybe a bit average.

I need to check on the A7, but on the A7R it has pretty strong green cast to the corners/edges and soft corners at most settings before 50mm or so. Doing side by side with my current 28-70mm and it is better, but still feels like a kit lens. I think 28-70mm on A7 is about like 24-70mm on A7R. The build quality of the 24-70mm f/4 is very nice though.

My comments was just based on pictures in the original post.  I don't have the lenses or A7 or A7r.
