Hi!
I have been using this camera for many years.
If you go for a telephoto lens, you can focus telephoto lenses with focal lengths over 300 mm with the universal leather bellows of the 4x5" F-metric Field.
For example I use a 360 mm tele-arton that requires only 210 mm of bellows draw at infinity.
Probably the longest focal length you can use among modern LF lenses is the Schneider 400 mm apo tele xenar with a flange-focal distance of 285 mm.
