The vignette you see is from the Sigma 30mm F2.8 APSC lens.
I haven't yet removed the baffle on this particular lens,
but I eventually will when I find the appropriate screwdriver.
The Sigma 2.8 30mm Art DN lens is my favourite lens to use on Sony full frame.
It is why I have an A7R - so I can crop with this lens to remove most of the vignette.
It is a very 3 dimensional picture this lens makes,
that and the colouring and rendering it does I am rather fond of on Sony cameras
- especially wide open at F2.8.

You can see the ceiling lamp and the window reflected in Woody's eye.
And this is just a JPEG, not a raw file.
