The C-1, aka "The Green Monster" is a wonderful instrument. 34" of bellows draw and light weight coupled with rigid construction and positive locks makes this camera a pleasure to use. I have the 8X10, 5X7, and 4X5 backs with my rig. The only drawbacks - no rise/fall on the rear standard and the 4X5 reduction back is a spring back (with bail), so Graflok accessories (such as roll film holders) can't be used. Calumet does make a nice rollfilm holder that works on all of their 4X5 cameras, so it isn't THAT big of an issue.
