Thanks, Mike. I appreciate you helping me on this. I waiting on a 90mm lens to arrive in the mail. Since there is not a 90mm increment I assume the process is to set infinity (and infinity stops) and then establish near focus, utilizing the "free scale" on the right side of the flatbed to tape and mark the focal lengths. Right? Would you happen to know what the approximate near focus would be with a 90mm Fujinon SW f8?
