I have shot the 120 on 8x10 a LOT. it covers, but not by much. I have shot the 120 on 4x10 a LOT more. I don't have any examples of 8x10 online, but my entire Utah Bigfoot series that I shot much of with the 4x10 is online. There are some examples of significant vignetting, but that was b/c of the Lee filter holder I was using (the rubber-band one...), and me getting sloppy/lazy.
