It's relatively compact- much smaller than a Mamiya RB/RZ camera- and while it doesn't have the rotating back and built-in bellows systems of those cameras

The heads can be controlled in two groups (A and B) from the power pack

Very minor focus distance plate "rubbing" means that this lens is a bit noisier during focusing and may not be suitable for video applications where absolute silence is required
