The Tilt/Shift Lens Adapter from FotodioX lets you mount a Hasselblad V lens to an L-Mount camera body and enables added levels of technical control. Providing a cost-effective alternative to tilt shift lenses, the adapter allows you to achieve selective focus as well as correct perspective distortion, such as in architecture photography.
The adapter attaches to the lens and camera the same way as a regular lens adapter, but you can then physically shift it left and right, push it up and down, or rotate it. Doing this tilts your focal plane and shifts your focus, allowing you to focus on just a small corner of a particular setting or on a specific subject while leaving everything else blurred. The adapter enables you to put your focus just about anywhere in the image. You can also capture the same image multiple times but with focus set in a different area of the image in each shot.
