For me, I have a Kolari V3 thin sensor modified A7r that I use with my 35mm f1.4 ZM Distagon lens which is normally used for landscape. But, it does require the usage of Corner Fix to remove the purple color issues and vignetting for the edges and corners. I could also use the lens with my stock A7rIII and live with stopping the lens down more.
As an option, when I want a tiny very light lens, I still have my Minolta CLE MC 40mm f2 Rokkor-M that does not require any usage of Corner Fix and color change and it performs a little better on the Kolari V3 thin sensor modified A7r (or stock A7r) or my A7rIII. But, it is not as good a lens as the Zeiss 35mm ZM.
