Paq Pro barrel and focus mount only:

Paq Pro barrels with new Rodenstock or Schneider focusing mounts will fit a specific current lens. To our knowledge, focusing mounts for older lenses are not offered. Occasionally, conflicting information may require your lens and body to be shipped to S.K. Grimes for fitting. See flange/focal information at these URLs:

If you don't know the Flange/Focal Distance for a prospective used lens you can save a lot of grief by using a new lens. In the event you buy a Paq Pro barrel with focusing mount for other than the lens it was made for, we do not offer any warranty and it cannot be returned. Best to send lens and components to S.K. Grimes for custom solution.
