My exact lens set for my Intrepid 8x10 Mark II. Coupled with a lightweight carbon fiber tripod and a couple of holders, and I can carry this outfit over any length of trail I'd care to hike.
I have the Fuji SWD 90/5.6 and I use it on 8x10 to make panormaics. It doesn't cover the corners of the sheet, but it will cover the full 10" width. The F8 version of the lens wouldn't inifinty focus on my camera, but the 5.6 will.
It makes a 6x25 pano much cheaper than either a Fuji or Linhof 6x17.
