I have my 5X7 Kodak 2D on a Berlebach tripod with a Bogen 3047 and sometimes I use the Manfrotto 410 with it and thoroughly enjoy the camera. The extension rail makes it sing, I got lucky and the original extension rail came with it and the racks match and are smooth. Someone before me put a new bellows on it but instead of the full length it is only 21". There is some rail left over when fully extended. That's minor though, I can fully use the camera in any extension with no leaks. The only thing I don't have is the base slider that repositions the camera on the tripod head. I intend to make one for it, it's really simple to make.
I made an adapter, 4 1/2" Sq. to Linhof, that uses the cameras original hardware without modifying the camera any. I like to use some lenses on it that I use on my 4x5 which takes only Linhof boards. Those which don't fit on Linhof boards go on the 5X7 board and they can be used on my Calumet 8X10 and 8X10 Kodak 2D cameras with another adapter, 6X6" to 4 1/2"X4 1/2" board. I can further use say my Schneider Symmar 210mm, which is on a Linhof board, on the Calumet C1 8x10 with the 8X10 to 5X7 reducing back from Calumet on it.
Have fun with the camera, I get a lot of comments when I'm out photographing with it.
