The Zörk Multi Focus System consists of an innovative, ball-joint design and precision helical tube that provides continuous focusing from infinity to macro range. This extremely versatile design, allows mounting on a variety of digital and film cameras. The MFS uses enlarger and large format lenses with 39mm thread.

. . . so enter the Zork MFS, the most extreme tilt lens on the market . . . The Zork is basically a rotational ‘tilt tube’ that uses a rather unconventional lens to give a staggering 20mm of tilt in any direction (most tilt lenses only give a maximum of 8mm locked on one axis). Not only is this useful for making miniaturizing effects, but the Zork is a killer macro lens like no other - David Clapp
