As for using roll film backs with the Tachihara, I wouldn't make that a determining factor, just get a Sinar or Calumet slide in back and you're set. I have and use both on my Tachi. Like the Tachi very very much, but agree that you may augment your gear in other ways with the money. B.t.w., is there any difference between the Tachi and the Shen in terms of the longest lens you can use? The Tachi is limited to about 300mm, which you may find to be an issue.
