This 645 accessories brochure ("Tools of the Trade") from Mamiya indicates that the extension tubes may be used with all lenses from 55mm, except zooms and that some vignetting may occur with lenses longer than 150mm .

“Photography is a complex and fluid medium, and its many factors are not applied in simple sequence. Rather, the process may be likened to the art of the juggler in keeping many balls in the air at one time!”
Ansel Adams, from the introduction to The Negative - The New Ansel Adams Photography Series / Book 2
