Note that while there is a smaller Speed Graphic, these medium format lenses will not fit, they need the 4X5 size camera to get a sufficiently large lens board for the bayonet mount.
So it seems, but there's a way to do it. In essence, attach the female bayonet to a stepped tube that in turn attaches to the lens board. I've done this with several lenses. You might want to take a look at my lens diary, it is at http://www.galerie-photo.com/telecha...2011-03-29.pdf
