It is a manual focus, special effect lens, mounted in a flexible housing which allows it to be focused and tilted at the same time. One can shift the focus to the side of the lens making for some very dramatic effects. I like to call it, "bending the light". An very interesting aspect of the lens, is the way the aperture is changed.
One just drops in one of a supplied aperture-rings to increase or decrease the opening (aperture) of the lens. Very unique!
Towards the end of the shoot I unfortunately lost one of the metal posts to fix the tilt... I emailed lensbaby with the request for sending me a replacement one and they replied within a few hours that one would be on the way shortly from the US. What a great service!
