The Kirk website indicates that the L bracket is for both cameras- 7/7II. Unless I am mistaken, both cameras have the same layout so I can not see why the bracket would not work with the 7. Additionally, m_liddell confirms that it fits his Mamiya 7.
Interesting. I'll have to take a look see when I get back to Boston this weekend. As I recall, the M7II has the camera strap in a different place than the M7 and the Kirk L has a small bolt that attaches indirectly to the strap (making the L plate much more rigid).
Is it that you forgo the little bolt and let the "L" float freely when used w/ the M7? Or do I have an early model that has been superceded with an updated L bracket that now supports both camera bodies?
Note: I also own the original Kirk M7 base plate which is appropriately mounted to my M7, so I'm defintely familiar with their "older" products and may not be totally up-to-date with their newer products.
Cheers,
