The Zörk Multi Focus System (MFS) is a compact, versatile, precision-built modular tilt/shift/macro system, consisting of shift adapters and extension tubes. The Zörk MFS uses an ingenious Tilt Tube® that provides up to 30° of tilt / swing along any axis, through 360° of rotation. This range of movement is unattainable in dedicated tilt lenses DSLR camera systems. The MFS uses a helical focusing tube in conjunction with a "short mount" APO Rodenstock lens, offering continuous focusing from infinity to 1:2 on a full frame DSLR. Add extension tubes, and the MFS will provide up to 3:1 image magnification, along with tilt / swing adjustments. The system is in perfect working condition and the lens is in perfect optical condition.
