Well, how about that. Dug out the Fuji lit. The IC is 305mm for the older lens. Despite this, Fuji does say the "Recommended for film size (f22)" is 8 x 10.
Also, bear in mind, that's at f22 and the lens stops to 64. Plus, those figures are for infinity. As you move closer to your subject, the image circle will increase.
So, I'll modify my original post and say: "It depends." :-)
