Thanks Robert, makes sense.

BTW, I've never used a Mamiya 220 or 330 before. I have a 7 and love the mamiya lenses.
How would you rate the TLR lenses? Remember, I'm a Rolleiflex 2.8 Planar user as well as a new 7....

I just like the bellows and that close up ability without the need for close up attachments...
