Product information "Format-Reduktionsplatte 4x5 - 6x9"
This is how you turn your 4x5" camera into a 6x9cm camera. You reduce its format frame from 4x5" to a 6x9cm format frame.
Lens rail: my recommendation is have your lenses mounted on a 110 x 110mm lens board as a matter of course and then work with the ARCA-SWISS reduction plate - that saves an unbelievable amount of carrying space, if, like every architectural photographer, you have a lot of lenses in your case.
Focusing screen rail: if you want to connect a digital back to your 4x5", the ARCA-SWISS reduction plate is the first accessory that you need.
In addition, you need an adapter (usually Hasselblad V or Hasselblad H) by means of which the corresponding back is attached to the ARCA-SWISS. To adjust the focusing screen, the ARCA-SWISS focusing screen frame with direct connection and Fresneldisc is essential.
