GFX 100S w/h Canon TSE 90/2.8 Macro

[kuau]

I am thinking about getting back into the "quasi" Medium format territory after a 10 year hiatus. I am currently renting for the week a GFX100S, 35-70 zoom and the Canon TSE 90/2.8 Macro along with the FotoDiox Adaptor.
To my surprise when I do a 3 shot stick pano with the 90 I don't see any corner vignetting maybe just a slight drop off in the extreme corner yet I can't even notice it. Does this sound right?
I have the GFX set to 4:3 ratio not 35mm crop and also the adaptor is set to "Medium Format" and wow I am pretty impressed. I am getting about a 155mp pano from 3 images just using the pano feature in LRC.
Tell me I am not doing it right??
I assume if I had the Canon TSE 50 Macro I would see some more vignetting when fully shifting??

It has a 88mm image circle for movements so its not surprising.

I have the old version which isn't very expensive and your observation sounds right. I think it is a nice lens for product photography and occasionally for portraits. Using the movements without vignetting is more limited than on a FF camera of course. An alternative would be an old MF lens with a T/S adapter which would give you the same kind of results with more movement.
