I just realized! I should have mentioned, this is with the Schneider 4B 2x center filter that I use for both my 72XL and 90XL. Fall-off will be an issue with this lens on such a wide format, as one would expect.

consummate_fritterer - regarding the crop, I have a friend who advised Clyde Butcher on some camera gear and I believe, but can not confirm, that some of his extremely wide images made on 8x10 are with the 90mm XL cropped to a panoramic-esque aspect ratio - 3:5 or so IIRC. I can't remember what AR I ended up printing that image to. I made one inkjet print for a show last year and it sold so I no longer have it.
