It should work fine with the same restriction as a normal camera (any 1s exposure of a moving object will get blurred to some extent). As long as it is a object like a seascape.
Remember that the lens is moving at a set speed. Had the camera recorded one slice of the picture and the jumped to the next one you would have had a problem with a moving sea.

If you are thinking about photographing a moving person or any smaller kind of object it will require a lot of planning when using a swing lens camera.
I'm using both a Widelux and a Noblex and I am very happy with both of them.
