The Mamiya Auto Spacer for Short Barrel Lenses is designed for use with the Short Barrel Lenses.
It provides for the full focusing range of the Short Barrel lenses, making them equivalent to the standard lenses of equal focal length
When using the Short Barrel lenses without the Tilt/Shift Adapter or Spacer the bellows must be extended 27.5mm to reach infinity focus
This distance is the same distance provided by the Tilt/Shift Adapter or the Spacer
