Hasselblad Xpan with 30mm parralax?

[njrfotografia]

Hi
Can somebody with the knowledge please explain the parralax issue with the Hasselblad Xpan 2 when using the 30mm?
How do I account for it? What does it effect and when does it take effect?
I primarily use my Xpan for landscapes but want to try using it for some street photography and heard parralax comes into play at focal distances of six feet or closer.
Thanks in advance

Do you have the manual for the 30mm lens? If so there are some diagrams on the pull out section in the back showing the parallax off set at closer focussing distances.

If you don't have the manual there is a version available in french here, which has the diagrams on the last page.
