find out the total extension--judging by the size it's just over 30"--you can easily do portraits with this. I have one similar and it has 33" extension I think. Oh--another thing..them rear extensions are useless on big cameras like this--they flop and wobble with the back way out there. Stick in a film holder and the back moves significantly--and it sways like a pendulum. That's what you get when you stick a heavy weight far out--a pendulum. You want that back as close to the base of the camera and tripod mount as possible. This design is actually superior for rigidity--the lighter weight lens moves out and keep the back fixed at the support as rigid as possible.
It provides plenty of vertical movements. It likely has just over 30" extension judging by the size of the format and the bed. You will almost certainly never have a need to use left right swing movements in this format, so you likely will not miss them. I'm thinking of getting it myself--it looks like it folds up smaller than the one I have.
