[QUOTE="STM, post: 734923, member: 12827"] Using the standard formula for magnification, Bellows extension/focal length, you would need about 400mm of bellows extension to get to about 12x. You can add about 2x +/- for reversing it. I don't know of any bellows that allow that much extension short of a 4x5. The PB-6 only allows about 215mm of extension. I added two PK-13's to the bellows to get the extension I did for this one. [/QUOTE]
