VC 21mm 1.8 + Close Focus Adapter on A7?

[NicoM]

I read a comment on a dpreview thread that the VC 21mm 1.8 with the new close focus adapter does not show any visible vignetting or colorshift on the edges of the frame.

Does anyone here have any experience with this combo?

I have the VC close focus adapter and it works great with my 28F2 Ultron but that is the widest i have at present
