Isn't this just a smaller version of the design they use for their 5x7 and 8x10 cameras? I'm not saying that they invented that design obviously, but it seems to me less like a ripoff of a Chamonix and more like they just decided to make the design of their larger cameras available in 4x5. Although maybe the inspiration for that was the success of the Chamonix. Feel free to disagree, I haven't seen their larger cameras in person so I could be totally wrong...

PS - It looks like it will be very nice to use regardless.
